Abstract
A new laser oscillation device is provided which is capable of readily cooling down a laser medium without employing any large-size complicated separate or discrete devices such as fan blowers while at the same time improving the laser oscillation efficiency to thereby easily generate high-output laser light. To this end, a Lorentz force drive electromagnetic pump and a cooling device are provided in a way such that the Lorentz force drive electromagnetic pump is operable to drive the laser medium while allowing the cooling device to cool down the laser medium being driven.
Claims8
A laser oscillation device comprising:
- a positive electrode and a negative electrode which induce a discharge current therebetween;
- a cooled laser tube containing a laser medium;
- means for applying a magnetic field in a direction that is perpendicular to the discharge current in order to induce circulation of the laser medium in said cooled laser tube,
- wherein the circulated laser medium is cooled by an inner wall of said cooled laser tube.
