Paper Abstract

Fundamental 1064 nm wavelength radiation of a diode pumped passively Q-switched Nd:YAG microchip laser was frequency doubled by periodically poled (PP) and conventional type II KTP crystals. Second harmonic (SH) conversion efficiency of 60% and 47% has been achieved with PPKTP and KTP crystals, respectively. SH pulse energy of as much as 6 μJ, at 900 Hz repetition rate, has been obtained for 10 μJ pulse energy of the input 1064 nm radiation focused with a waist radius of 25 μm inside the 8 mm long PPKTP crystal. We estimated an effective nonlinear coefficient of 6.9 pm/V and a thermal acceptance FHWM bandwidth of 5.78°C for the PPKTP sample.
