Blue-green light generation by self-sum-frequency mixing Nd:YCOB laser

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:YCa4O(BO3)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 M2 value is 1.22 in both hori...

Zusammenfassung:	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:YCa4O(BO3)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 M2 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.
