| Popis: | A single-color circularly polarized laser beam is focused into pressurized hydrogen to generate rotational stimulated Raman emission. After being corrected to a linearly polarized beam, this two-color laser beam is passed through a dye amplifier and is focused into pressurized hydrogen, again to generate multifrequency laser emission by the two-color stimulated Raman effect. The laser beam is further confined in a resonator, which enhances intracavity intensity leading to increased efficiency. In these experiments, more than 11 rotational lines are generated simultaneously at 5 atm, and many additional vibrationally shifted rotational lines are generated at 9 atm. |
