Abstract
An intracavity doubled solid state Raman laser system for converting the frequency of a laser input beam emitted by a laser pumping system is described. A solid Raman medium is disposed within a resonator cavity to shift the frequency of the input beam to produce a Raman beam. The frequency of the Raman beam is tuned in the resonator cavity preferably using an etalon and a birefringent filter. The polarization of the Raman beam is selected using a polarizing element disposed in the resonator cavity. The Raman beam frequency is doubled using a non-linear doubling medium inside the resonator cavity. The Raman laser system is particularly suitable for producing yellow light.
