Abstract
The possibilities of improvement of laser emission characteristics and reduction of heat generation by direct pumping at 887 nm into the emitting level F43/2 of Nd3+ in the self-frequency-doubling crystal Nd–GdCOB [GdCa4O(BO3)3] are discussed. Enhanced laser emission performances at fundamental 1060 nm, and especially at the self-frequency-doubled 530 nm wavelengths as compared to the traditional 811 nm pumping into the F45/2 level, are demonstrated.
