PURPOSE:To realize a Raman laser having he average output by introducing gas carbonate laser light into a Raman cell so as to generate secondary inductive Raman dispersion. CONSTITUTION:Laser light is synchronized with a primary stokes light length. Laser light outgoing therefrom is superposed on the gas carbonate laser light and introduced into a Raman cell. A Raman cell part 5 has a multiplex reflection optical system and a gas cooling mechanism. Heavy hydrogen gas or pure orthoheavy hydrogen gas is used as a Raman medium. The multiplex reflection optical system makes two convex mirrors to face each other for making a laser beam to perform multipath reflection therebetween. Thereby, an effective Raman medium length is increased. Further, at every one time reflection, a laser beam is subjected to focusing and also thereby Raman conversion is promoted. Then, a laser pulse transmitted through this Raman cell part 5 is converted into 16mum light through secondary dispersion process. |
