4 March 2016High-repetition rate, picosecond-pulse, tunable, mid-IR PPLN OPG source
We report here on the performance of a narrow-line, mid-IR source based on a PPLN-crystal optical parametric generator (OPG). The crystal was pumped by a pulsed, 20-MHz-rate, 1064-nm Yb:fiber-based source operating with 20- psec pulses. The OPG produced a broad spectrum between 2027 nm and 2239 nm. By placing a band-pass filter after the OPG we were able to select a 30-nm bandwidth output, and we achieved further line reduction (0.7 nm) and 4.5 mW of average power at 2039 nm, using a reflective Volume Bragg Grating (VBG). Devices such as piezo-controlled etalons can provide rapidly tunable, narrow-linewidth power from this system.
