This manuscript provides a comprehensive review of the characteristics of Cr4+-doped solid-
state lasers which produce broadly tunable coherent radiation in the near-infrared region of …

This review provides an overview on the subject of Cr4+-doped solids and their numerous
applications in laser physics, technology, and industry. The transition metal ions have …

In this work an overview of transition metal (TM) ion-and rare earth (RE) ion-doped crystals
for application as tunable solid-state lasers will be given. Spectroscopic and laser results will …

This book examines the underlying science and design of laser materials. It emphasizes the
principles of crystal-field engineering and discusses the basic physical concepts that …

Lasers continue to be an amazingly robust field of activity. Anyone seeking a photon source
is now confronted with an enormous number of possible lasers and laser wavelengths to …

We demonstrate the performance of a Nd: YAG laser, passively Q-switched with a Cr/sup
4+/: YAG plate, which plays the double role of a passive Q-switch and a Brewster plate. The …

We present a spectroscopic overview of Cr 4+-doped Y 3 Al 5 O 12 (YAG), a new laser
material for the near-infrared region (NIR). It is found that only 2% of the Cr ions are …

This book describes in detail the main concepts of theoretical spectroscopy of transition
metal and rare-earth ions. It shows how the energy levels of different electron configurations …

Thermal treatment of YAG crystals co-doped with Cr4+ and Ca2+ exhibits reversible
oxidation–reduction reactions of the chromium ions, which depend on both temperature and …

The design features of, and first observations from, a new elastic backscatter lidar system at
a wavelength of 1543 nm are presented. The transmitter utilizes stimulated Raman …
