Periodically poled 5% MgO doped lithium niobate (PPMgO:LN) crystals for second harmonic and other quasi‐phase‐matched nonlinear optical applications.
The single‐pass efficiency of 60‐70% and average power more than 10 W of green light in pulse regime were demonstrated and confirmed by our customers in 5 mm length crystals for frequency doubling of 1064 nm laser light.
