Document Type and Number:
Japanese Patent JP4387598
Kind Code:
B2
Abstract:
The present invention relates to laser devices with increased cooling capability by means of largely extended cooling surfaces contacting the laser active medium. According to the present invention there is provided a laser device comprising a large active volume in conjunction with a compact structure of the device and outputting single mode radiation. The laser device according to the present invention comprises the following features. A laser active medium, an optical resonator system defining an optical axis, exciting means for exciting said laser active medium and enabling a stimulated emission of radiation of said laser active medium, and cooling means, having first and second cooling elements arranged in spaced opposing relationship with surfaces facing each other, wherein said laser active medium is provided between said cooling elements along said optical axis. In order to increase the output power and to obtain single mode radiation an optical element is provided, arranged within the optical path formed by said optical resonator system and having a refractive power in a first plane, along said optical axis and perpendicular to said surfaces, differing from a refractive power in a second plane, along the optical axis and perpendicular to said first plane, wherein a contact of a laser beam deflected in said first plane with said surfaces of said first and second cooling elements is avoided.
