Abstract

A comparative research into the use of Cr⁴⁺-doped YAG, YSGG, and LuAG (Lu₃Al₅O₁₂) as saturable absorbers for the 1.06 micrometer emission of Nd:YAG laser has been conducted. Q-switched pulses with temporal duration ranging from 52 to 23 nsec (FWHM) were observed for the different garnets under investigation. Cross-sections for ground state and excited state absorption were evaluated by fitting our saturation data to Frantz-Nodvik equation. A brief discussion on the use of Cr⁴⁺ as a tunable mid-IR laser also is presented.
