Bow-Tie cavity design for high power SHG green laser. A high power fiber laser at 1064nm is terminated into an external bow-tie cavity for efficient SHG generation at 532nm green.

1. SHG Bow-Tie Cavity Design

2. The Design provides an excellent mode and impedance matching with a
power buildup factor of 21 and overall conversion efficiency of 40% at
532nm.

3. The high power fiber laser provides a 100W of CW power at 1064nm
which is subsequently converted to 40W of 532nm.
