A comparative study of a frequency-doubling 532 nm laser based on gray-tracking-resistant KTP (GTR-KTP) and conventional KTP is presented. The intracavity GTR-KTP was proved to have better temperature characteristics than that of conventional KTP. Within the normalized output power variation range of 0.8–1.0, GTR-KTP has a temperature tolerance of 35 ° C , broader than the 21 ° C obtained with conventional KTP. Under the laser diode (LD) pump power of 180 W , the maximum average output power at 532 nm was 40.6 W for GTR-KTP at a repetition frequency of 10 kHz . In the case of conventional KTP, the maximum available LD pump power was limited to 150 W , with the corresponding maximum green average output power of 27.2 W .
