An $\alpha\hbox{-}{\rm BaTeMo}_{2}{\rm O}_{9}$ Raman Shifting Driven by a Pulsed LD Pumped Nd:YAG Laser

We reported a compact α-BaTeMo

O
₉
Raman laser driven by a pulsed laser diode (LD) pumped Nd:YAG/ Cr
⁴⁺
:YAG laser for the first time. A maximum pulse energy of 1.07 mJ at 1177.8 nm was obtained with the absorbed LD pump energy of 10.63 mJ, giving an optical-to-optical conversion efficiency of 10% and a slope efficiency of 13.8%. The pulse output characteristic of the Raman laser was analyzed in detail.
