Thermal effect depends on focus position in CW single-pass high power SHG in PPMG:SLT

We investigated the properties of single-pass second-harmonic generation of CW 532 nm radiation with a single frequency Nd:YAG laser by QPM in Mg:SLT. SHG upper limit can be increased by shifting the focus position.
