Abstract
A method and apparatus for obtaining multiple wavelengths of varying temporal format from a single solid state laser are provided. Accordingly, the output from the solid state laser can either be sent through a series of non-linear crystals to obtain UV radiation or through an OPO cavity to obtain IR radiation. In order to provide the different wavelengths in the temporal formats commonly used for various medical procedures, the laser source may be operated in two different modes. When the laser system produces UV radiation a pulse of short duration is desired and the laser source is operated in the standard Q-switched mode or is mode locked. Conversely, when the laser system produces IR radiation, a pulse of long duration is desired and the laser source is operated in the free running mode. The outputs from the UV and IR portions of the system can either be directed to the object to be treated through a common beam delivery system or through separate beam delivery systems, for example utilizing optical fibers or waveguides.
