Continuous-wave dual-wavelength operation at 1062 and 1338nm in Nd3+:YAl3(BO3)4 and observation of yellow laser light generation at 592nm by their self-sum-frequency-mixing

Abstract We report simultaneous oscillation in continuous wave at 1062 and 1337 nm in a Nd 3+ :YAl 3 (BO 3 ) 4 nonlinear crystal associated to the infrared laser channels 4 F 3/2  →  4 I 11/2 and 4 F 3/2  →  4 I 13/2 of Nd 3+ . Generation of yellow laser light at 592 nm produced by Type I self-sum-frequency-mixing of both fundamental infrared laser waves is observed under non-optimal phase matching conditions.
