✦ Synopsis

We report a coherent blue-green radiation at 497 nm by self-sum-frequency generation of the 936 and 1060 nm laser-lines of the Nd:YCa 4 O(BO 3 ) 3 (Nd:YCOB) crystal. With a diode pump power of 14.3 W, the maximum blue-green output power of 75 mW is obtained. The beam quality M 2 value is 1.22 in both horizontal and vertical dimensions. The output power stability over 30 min is better than 4.1%. To the best of our knowledge, this is first work on self-sum-frequency generation of a diode pumped Nd:YCOB laser at 497 nm.
