We demonstrate the ability to generate ultra-high-frequency sequences of broadly wavelength-tunable, high-intensity laser pulses using a custom-built optical parametric oscillator pumped by the third-harmonic output of a "burst-mode" Nd:YAG laser. Burst sequences consisting of 6-10 pulses separated in time by 6-10 mus are obtained, with average total conversion efficiency from the 355 nm pump to the near-IR signal and idler wavelengths of approximately 33%. Typical individual pulse output… CONTINUE READING
