US 5,636,238 A · Device for producing laser radiation at a variable or selectable wavelength

Abstract

A device permitting a single primary laser producing a collimated beam at a given wavelength, to be used for different purposes by converting the collimated beam to a beam of different wavelength. The device comprises a secondary laser disposed within a body removably attached to the distal end of an articulated arm delivery system attached to the primary laser. Preferably, the secondary laser is interchangeable with respect to the delivery system thus to extend the wavelength (color) coverage of the primary laser according to the required wavelength conversion. The secondary laser may include an optical crystal or a circulated organic dye solution within a removable cell or reservoir. Appropriate lenses are provided to focus the primary beam and to determine the spot diameter of the conversed beam.

Dependent claims

A device for producing laser light of a selectable wavelength comprising a primary laser;

a multi-directional delivery system, the delivery system including a linear articulated arm;
and a conversion device, the conversion device comprising a secondary laser having a lasing medium incorporating a fluid, and a circulation device further including spinning means disposed within the fluid for fluid circulation, the circulation device having a motor magnetically coupled to the spinning means for powering the spinning means, wherein a beam of primary laser light emitted from the primary laser is transmitted through the articulated arm and received by the conversion device, which emits a secondary laser beam of a different wavelength.
