Over the past two decades, fiber laser technologies have matured to such an extent that they
have captured a large portion of the commercial laser marketplace. Yet, there still is a …

ZBLAN (ZrF4‐BaF2‐LaF3‐AlF3‐NaF), considered as the most stable heavy metal fluoride
glass and the excellent host for rare‐earth ions, has been extensively used for efficient and …

The transmission and processing of signals carried by optical beams rather than by
electrical currents or radio waves has been a topic of great interest ever since the early …

Yellow lasers (∼ 565–590 nm) are of tremendous interest in biomedicine, astronomy,
spectroscopy, and display technology. So far, yellow lasers still have relied heavily on …

Tunability has added an important dimension to a variety of laser devices and led to new
systems and applications. From laser spectroscopy to Bose-Einstein condensation, the one …

Since the first invention of the laser in 1960, direct lasing outside the fluorescence spectrum
is deemed impossible owing to the “zero-gain” cross-section. However, when electron …

William Risk, Timothy Gosnell and Arto Nurmikko have brought together their diverse
expertise from industry and academia to write the first fully comprehensive book on the …

The fiber laser, with its humble beginning in the late 1980s, has undergone tremendous
development in the past decade or so, transforming itself from a research curiosity to a major …

We review progress in the development of an unconventional type of semiconductor laser
that has become the focus of much attention in recent years. The vertical-external-cavity …

Surface-emitting semiconductor lasers can make use of external cavities and optical
pumping techniques to achieve a combination of high continuous-wave output power and …
