Abstract

We report what is to our knowledge the first directly diode-pumped tunable (over 120 nm) continuous-wave Cr4+: YAG laser, operating near 1.5 μm . At room temperature the laser delivered as much as 200 mW of power at 4 W of absorbed pump power. We also report observation of slow laser output degradation and bleaching in highly concentrated cyrstals, which we suggest is due to a photorefractive phenomenon.
