Abstract

High-repetition-rate generation of up to 325 mJ of Raman amplified radiation near 615 cm-1 has been demonstrated in CO2-pumped para-H2 using a low-power, microwave-shifted CF4 laser as an input Stokes seed source. Experiments were limited to 200 Hz, but single-shot Schlieren measurements indicate that our flowing room-temperature 44-pass Raman con-verter should be capable of the design goal of 1 kHz. Strong conversion was achieved even with no flow at 100 Hz. Details of the overall system design, experimental parameters, and present system limitations are discussed.
