Paper Abstract

We report the operation of an optical parametric oscillator (OPO) at 1574 nm using KTP, with output peak power of more than 5 megawatts, output pulse energy of up to 30 mJ per pulse, pulse width of less than 6 nanoseconds at full width half maximum (FWHM) and operating frequency of 30 Hz. The OPO was pumped by a diode pumped Nd:YAG Q-switched laser, with pump energy of about 95 mJ and pulse width of approximately 7 ns. The conversion efficiency from 1064 nm Nd:YAG laser to OPO output at 1574 nm is more than 30%. The whole system including the Nd:YAG laser was compactly packed inside a case measuring 15" x 9" x 5.3". The complete OPO system was tested over an operating temperature range of -20 °C to +35 °C and a storage temperature range of -40 °C to +50 °C without significant power or performance variations, which makes it suitable for field operation.
