Diode-Laser-Array Single-End-Pumped 5W Nd:YVO 4 /KTP Continuous-Wave Solid-State Green Laser

Continuous-wave radiation of 5 W at 532 nm was produced with an Nd:YVO 4 /KTP intracavity frequency-doubled laser end-pumped by a diode-laser-array at pump power of 17.2 W, giving optical conversion efficiency of 29.1%. The output power stability was measured to be better than 1.5% in short term operation. The pump-induced thermal lensing was also measured, showing good agreement with the performance of the laser.
