Abstract
A laser system having plural optical paths, each with a dielectric mirror for extracting a different wavelength of light from a laser beam, and a laser medium movable with respect to the different optical paths for injecting the laser beam into a desired optical path. The laser medium is mounted to a motor driven carriage for moving the laser medium with respect to the different optical paths.
Claims23
A laser system adapted for generating plural wavelengths of light, comprising:
- a laser medium having a longitudinal axis for generating a beam of light;
- a pair of different sets of optical elements defining a first linear pathway parallel to the longitudinal axis and a second linear pathway parallel to the longitudinal axis, each pair of optical elements sets being responsive to the beam of light for producing respective different wavelengths of light;
- and
- means for selectively directing the beam of light with respect to the first linear pathway and the second linear pathway for generating a desired wavelength of light.
A laser system adapted for generating plural wavelengths of light, comprising:
- a laser medium for generating a beam of light;
- a plurality of different optical elements defining different pathways, said optical elements being responsive to the beam of light for producing respective different wavelengths of light;
- means for selectively directing the beam of light with respect to the different optical elements for generating a desired wavelength of light;
- and
- means for moving the laser medium with respect to the different optical elements to select a pathway.
A laser system adapted for generating plural wavelengths of light, comprising:
- a single laser medium for generating a beam of light;
- a plurality of pairs of mirrors, each pair responsive to the light beam for extracting a different wavelength of light, and each mirror of a pair being disposed at opposing ends of the laser medium;
- and
- means for moving the laser medium to respective locations between a selected pair of said mirrors;
- and
- means operable by a user of the system to selectively position the laser medium to thereby generate a desired wavelength of light.
A method for constructing a laser system capable of generating different wavelengths of light, comprising the steps of:
- arranging a plurality of sets of mirrors to form a plurality of optical pathways, at least one mirror in each set of mirrors capable of extracting a predefined wavelength of light from the system;
- fixing a laser medium capable of generating a plurality of distinct wavelengths of light to a carriage;
- and
- coupling a motor with respect to the carriage so that in response to electrical signals the motor moves the carriage for aligning the laser medium with respect to a desired optical pathway.
