Abstract
A hand-held laser device includes a casing formed with a substantially hollow interior space and having a laser emitter thereinside. The laser emitter is formed with an exciting lamp and a laser rod. A source generating a stream of gaseous coolant is provided within the interior space. A fluid cooling arrangement at least partially surrounding the laser rod is disposed within the stream of gaseous coolant for heat removal therefrom.
Claims10
A cooling arrangement for a hand-held laser device, comprising:
- a laser emitter formed by at least a laser rod and an exciting lamp spaced from each other;
- a jacket defined by at least spaced from each other exterior and interior walls thereof, a longitudinal opening extending through said jacket and defined by said interior wall, said longitudinal opening being adapted to rotatably receive said laser rod;
- and
- a continuous internal spiral groove formed within a body of said jacket at said interior wall, so as to provide positive displacement of a cooling fluid within said internal groove about an outer periphery of said laser rod during rotation of said jacket about said laser rod.

A cooling arrangement for a laser device comprising:
- a laser emitter formed by at least an exciting lamp and a laser rod spaced from each other;
- a jacket stationarily positioned with respect to said laser rod unit, said jacket having a longitudinal interior opening extending therethrough to receive the laser rod;
- and
- a continuous spiral arrangement is provided in the body of the jacket at an outer periphery of the laser rod and extending outwardly therefrom,
- whereby rotational motion of the continuous external spiral arrangement provides a rotary positive displacement of a cooling fluid along said laser rod.
