Laser Design and Applications

Experimental results are presented on stimulated Raman scattering of short pulses of approximately 100 ps duration in H 2 , D 2 , and CH 4 , both in capillary waveguides and in a tight focusing geometry. Experimentally determined thresholds are in good agreement with calculation. Low thresholds ( < 20 \mu J) are observed in CH 4 and preliminary results using a mode-locked dye laser as pump indicate a useful source of tunable short pulse radiation in the near infrared.
