48 W, 5 ps, 100 kHz Ho:YLF CPA system and its application to mid-infrared ZGP OPG/OPA
Abstract:
In this Letter, we report a high-power, high-repetition-rate Ho:YLF chirped-pulse amplification (CPA) system driving a ZnGeP2 (ZGP) optical parametric generator and amplifier (OPG/OPA). The Ho:YLF CPA system operates at 100 kHz, delivering 48.1 W of average power at 2050.8 nm with a compressed pulse width of 5.0 ps. Using this source to pump the ZGP OPG/OPA, we obtain a 2.7 W signal light at 3402.1 nm and 0.64 W idler light at 5160.3 nm, with a pulse width of 2.5 ps for both. Moreover, continuous wavelength tuning ranges are achieved over 3051.2-3900.2 nm for the signal light and 4205.1-5160.3 nm for the idler light.
