Laser Technology in Biomimetics
by Volker Schmidt Maria Regina BelegratisLasers are progressively more used as versatile tools for fabrication purposes. The wide range of available powers, wavelengths, operation modes, repetition rates etc. facilitate the processing of a large spectrum of materials at exceptional precision and quality. Hence, manifold methods were established in the past and novel methods are continuously under development. Biomimetics, the translation from nature-inspired principles to technical applications, is strongly multidisciplinary. This field offers intrinsically a wide scope of applications for laser based methods regarding structuring and modification of materials. This book is dedicated to laser fabrication methods in biomimetics. It introduces both, a laser technology as well as an application focused approach. The book covers the most important laser lithographic methods and various biomimetics application scenarios ranging from coatings and biotechnology to construction, medical applications and photonics.
The Laser That's Changing the World: The Amazing Stories behind Lidar, from 3D Mapping to Self-Driving Cars
by Todd NeffTells the story of a laser technology that will have a big impact on society and the brilliant innovators responsible for its developmentLidar--a technology evolved from radar, but using laser light rather than microwaves--has found an astounding range of applications, none more prominent than its crucial role in enabling self-driving cars. This accessible introduction to a fascinating and increasingly vital technology focuses on the engaging human stories of lidar's innovators as they advance and adapt it to better understand air, water, ice and Earth - not to mention mapping Mars and Mercury, spotting incoming nuclear warheads, and avoiding pedestrians and cyclists on city streets. Award-winning science writer Todd Neff invites readers behind the scenes to meet some of the great innovators who have explored and expanded the uses of this amazing technology: people like MIT scientist Louis Smullin, whose lidar bounced light off the moon soon after the laser's invention; Allan Carswell, who plumbed the shallows of Lake Erie en route to developing the aerial lidar now essential for coastal mapping and hurricane damage assessment; Red Whittaker, the field robotics pioneer who was putting lidar on his autonomous contraptions as early as the 1980s; and David Hall, whose laser sombrero on a Toyota Tundra gave birth to modern automotive lidar.These are just some of the stories Neff tells before looking ahead to a future that could bring lidar to unpiloted air taxis, to the contaminated pipes of the U.S. nuclear weapons complex, and to satellites capable of pinpointing greenhouse gas sources from orbit. As the author makes clear, the sky is no limit with lidar, which promises to make our world safer, healthier, and vastly more interesting.
Laser-triggered Nanobiomaterials for Inhibiting Tumor Growth
by Maoquan ChuThis book focuses on laser-triggered nanobiomaterials for tumor inhibition. In this book, magnetic iron oxide nanoparticle-mediated cancer PTT through intratumoral or/and intravenous injection is introduced first. The benefits of intratumoral injection and the main factors affecting the retention of materials and permeability in solid tumors have been discussed. Furthermore, an attempt has been made to explore the performance of magnetic iron oxide nanoparticles after intravenous injection for tumor-targeted PTT based on several strategies. The latter part probes the gaps to improve magnetic iron oxide nanoparticle-mediated PTT through intratumoral and intravenous injection modes. This book also includes discussion on drug-loaded magnetic nanocomposites, magnetic iron oxide/Au nanocomposites, and magnetic iron oxide/semiconductor nanocrystal nanocomposites for combination cancer therapy, and enhanced cancer PTT has also been included as an integral part. This book also summarizes the most investigated photothermal agents, including noble metal nanoparticles, especially gold nanostars, hollow mesoporous copper sulfide nanoparticles, carbon-based nanoparticles, especially carbon nanotubes and graphic carbon nanocages, black phosphorous nanosheets, conjugated polymer nanoparticles, and organic dye nanoparticles. This book is useful for undergraduate and postgraduate students to better understand this research area. It may also provide useful information for technical nonspecialists whose background is in nanoscience and nanotechnology, biology, medicine, pharmacy, materials, chemistry, and physics.

Laser Wakefield Electron Acceleration
by Karl SchmidThis thesis covers the few-cycle laser-driven acceleration of electrons in a laser-generated plasma. This process, known as laser wakefield acceleration (LWFA), relies on strongly driven plasma waves for the generation of accelerating gradients in the vicinity of several 100 GV/m, a value four orders of magnitude larger than that attainable by conventional accelerators. This thesis demonstrates that laser pulses with an ultrashort duration of 8 fs and a peak power of 6 TW allow the production of electron energies up to 50 MeV via LWFA. The special properties of laser accelerated electron pulses, namely the ultrashort pulse duration, the high brilliance, and the high charge density, open up new possibilities in many applications of these electron beams.

Lasers, Death Rays, and the Long, Strange Quest for the Ultimate Weapon
by Jeff HechtThe whole story of laser weapons with a focus on its many interesting characters and sometimes bizarre schemesThe laser--a milestone invention of the mid-twentieth century--quickly captured the imagination of the Pentagon as the key to the ultimate weapon. Veteran science writer Jeff Hecht tells the inside story of the adventures and misadventures of scientists and military strategists as they exerted Herculean though often futile efforts to adapt the laser for military uses. From the 1950s' sci-fi vision of the "death ray," through the Reagan administration's "Star Wars" missile defense system, to more promising developments today, Hecht provides an entertaining history. As the author illustrates, there has always been a great deal of enthusiasm and false starts surrounding lasers. He describes a giant laser that filled a Boeing 747, lasers powered like rocket engines, plans for an orbiting fleet of robotic laser battle stations to destroy nuclear missiles, claims that nuclear bombs could produce intense X-ray laser beams, and a scheme to bounce laser beams off giant orbiting relay mirrors. Those far-out ideas remain science fiction. Meanwhile, in civilian sectors, the laser is already being successfully used in fiber optic cables, scanners, medical devices, and industrial cutting tools. Now those laser cutting tools are leading to a new generation of laser weapons that just might stop insurgent rockets. Replete with interesting characters, bizarre schemes, and wonderful inventions, this is a well-told tale about the evolution of technology and the reaches of human ambition.

The Last American Hero: The Remarkable Life of John Glenn
by Alice L. GeorgeOn February 20, 1962, John Glenn became a national star. That morning at Cape Canaveral, a small-town boy from Ohio took his place atop a rocket and soared into orbit to score a victory in the heavily contested Cold War. The television images were blurry black-and-white phantoms. The cameras shook as the rocket moved, but by the end of the day, one thing was clear: a new hero rode that rocket and became the center of the world's attention for the four hours and fifty-five minutes of his flight. He became celebrated in all corners of the world as not just the first American to orbit the Earth, but as the first space traveler to take the human race with him. From that day forward, Glenn restively wore the hero label. Wherever he went, people knew his name and what he had done. Refusing to let that dramatic day define his life, he went on to become a four-term US senator—and returned to space at the age of seventy-seven. The Last American Hero examines the many layers that formed the man and unravels the reasons for his singular role. He was a creation of the media, in some ways, but he was also a product of the Cold War. Not even Glenn himself seemed to fully understand his celebrity. He was a war hero, a two-time astronaut, a veteran senator, a devoted husband, a father, and much more. At a time when increasingly cynical Americans need heroes, his aura burns brightly in American memory.
