External cavity diamond Raman laser pumped by 8.3 ns (10 Hz) single frequency 532 nm pump was studied. The output energy of 4.2 mJ and 2 mJ at first (573 nm) and second (620 nm) Stokes, respectively, was demonstrated for 12 mJ of pump energy with the total conversion efficiency of 51%. The minimum first Stokes pulse duration of 420 ps in backward and 500 ps in forward directions were measured under 3.5 mJ of pump energy and 7.5 mJ (9 mJ) of output energy in backward (forward) Raman signal. |
