High-energy nanosecond parametric source at 2.7 µm
Abstract
We report a high-energy nanosecond K T i O A s O 4 -based optical parametric oscillator and amplifier system driven by a 1064-nm, injection-seeded, Q -switched Nd:YAG laser to provide mid-infrared pumping for few-cycle optical parametric chirped-pulse amplification operating in the long-wave infrared spectral regime. An output energy of 10.5 mJ at 2726 nm was obtained from the final power amplifier with a spectral width of 2.8 nm, pulse duration of 1.2 ns, and M 2 value of 2.4. The parametric source provides for the second mode of operation, where 10-ns pulses are produced by disabling the electro-optic slicing that enables the 1-ns mode. For 10-ns operation, the source produced energy of 25 mJ with a M 2 value of 2.8.
