摘要：

We report here the first evidence of blue light generation in a Nd:Ca4GdO(BO3)(3) (Nd:GdCOB) crystal by self-sum frequency mixing. More than 1 mW of cw 465 nm laser emission was achieved with 490 mW of absorbed pump power from a titanium sapphire laser (829.6 nm). The blue emission is nearly TEM00, and the laser threshold is very low (a few mW). The performance should be improved by the use of antireflection-coated crystals and suitable mirrors.
