|Title:||Diode-pumped Nd:YAG eye-safe laser|
Bhatt, S C
|Keywords:||Eye safe laser;Phase matching;Optical parametric oscillation (OPO)|
|Abstract:||Nd:YAG laser is pumped with two-dimensional side pumping diode-laser array. The wavelength from the Nd:YAG is 1064 nm, which is not safe for the eye. Here this eye hazardous laser is converted into the eye safe region using a singly resonant extra cavity KTP OPO. The output energy is an eye safe radiation at 1525 nm, with 8 mJ, corresponding to an energy conversion efficiency of 21 % at phase matching angle 210, in a type-II, NCPM x-cut KTP crystal (15 × 10 × 10 mm) placed in a plane-parallel resonator.|
