Reflecting changes in the field in the ten years since the publication of the first edition, The
Handbook of Photonics, Second Edition explores recent advances that have affected this …

Lasers with emission wavelengths of 1.5 μm are suitable for the eye-safe band and
transparency region of the atmosphere. During extremely bad weather conditions, the …

The optical properties and functionality of air-stable PbSe/PbS core− shell and PbSe/PbSe x
S1-x core-alloyed shell nanocrystal quantum dots (NQDs) are presented. These NQDs …

Published data on spectroscopic characteristics of saturable absorbers based on crystals
doped with tetrahedrally coordinated transition-metal ions (Cr 2+, Cr 4+, Cr 5+, V 3+, Cr 2+ …

A new saturable absorber Q switch for 1.54-µm Er: glass lasers is presented. The saturable
absorber is a transparent glass ceramic that contains magnesium–aluminum spinel …

A survey of results on use of semiconductor-doped glass saturable absorbers for near-
infrared passively mode-locked and Q-switched solid-state lasers is presented. Nanosized …

We demonstrate a compact laser source in the eye-safe wavelength regime (≈ 1.5 μm) that
produces peak powers up to 10.6 kW at pulse durations of 0.84 ns with a repetition rate …

Passive Q switching of a Nd 3+: YAlO 3 laser at 1.34 μm and an Er 3+: glass laser at 1.54 μm
was demonstrated using a Co 2+: LiGa 5 O 8 crystal as a saturable absorber. Q-switched …

The purpose of this presentation is to review the spectroscopic properties of the main laser
materials based on transition metal ions which lead to noticeable laser performance at room …

The absorption spectra of the 0.5 at.% and 1at.% Co: LaMgAl11O19 (LaMg1-xCoxAl11O19,
x= 0.005 and 0.01, abbreviated as Co: LMA) crystals were measured at room temperature …
