Abstract

We experimentally confirm a pump-induced loss in a Ti:sapphire laser pumped by 451- or 478-nm laser diode. Such loss is significant even for a crystal producing better output performance at 520-nm pumping. We demonstrate a power scaling of a CW Ti:sapphire laser using two 520-nm green diodes and two 478-nm blue diodes, and obtained an output power of 593 mW at an absorbed pump power of 2.5 W.
