Abstract
A two-stage Raman-conversion system pumped with a Q-switched alexandri te laser is proposed for the generation of broadly tunable infrared ra diation. The first stage is a high-pressure Raman cell which accepts a pump beam in long-focusing or parallel-beam geometry, while the succe ssive second one is made of a multi-pass Raman cell with repeated focu sing. Using a selected combination of vibrational or rotational Raman shifting by H-2, a spectrum ranging from 0.75 mum to 15 mum can be cov ered by this system.
