Flash-pumped pulsed Cr:LiSAF laser action from a modified conventional solid state laser cavity

Conventional solid state laser pumping cavities has been used, after proper modification, in order to achieve efficient laser action by Cr:LiSAF crystals. The crystal samples were placed in the laser head, properly supported for efficient pumping to achieve satisfactory laser action. It has been proved that for a successful result a strong flash pumping source and a low output coupling is needed to help the low overall gain of the small Cr:LiSAF samples.
