Abstract
The use and the spectral properties of Cr4+-doped garnets as passive Q-switches for 1.06 μm laser for both pulsed and CW operating modes is addressed. A comparative research into the use of Cr4+-doped YAG, YSGG and LuAG (Lu3Al5O12) as saturable absorbers for the 1.06 μm emission of Nd:YAG laser has been conducted. Q-switched pulses with temporal duration ranging from 52 to 23 ns (FWHM) were observed for the different garnets under investigation. Cross-sections for ground state and excited state absorptions were evaluated by fitting our saturation data to Frantz-Nodvik equation. A complete analysis of the saturation transmission curves will be presented. The laser performance of Cr4+:YAG and Cr4+:LuAG (Lu3Al5O12) lasing in the mid-IR (1.35-1.55 μm) pumped by the 1064 nm of Nd:YAG will also be reported.
