title: High-efficiency pulse compression with intracavity Raman oscillators.
abstract: High-efficiency pulse compression has been obtained by using an intracavity Raman oscillator. The energy of a primary laser stored in its high-Q cavity is extracted at the Stokes frequency by means of a Stokes laser having a high Raman gain and a low-Q cavity. This technique, using hydrogen gas as the Raman medium, permits shortening of the pulse duration of a ruby laser by a factor of 6.7 with 87% effective quantum efficiency. It would be especially useful with low-gain (alexandrite) and with short-storage-lifetime lasers.
