Abstract
A long wavelength NdYAG laser which is operable either in a surgical cutting mode where the wavelength of laser radiation is about 1.44 micrometers, or in a therapeutic coagulating mode where the wavelength of laser radiation is about 1.06 micrometers. The NdYAG laser combines the use of frequency selective laser mirrors together with a repetitively pulsed high peak current lamp to produce high laser power at both 1.44 micrometers and 1.06 micrometers. The NdYAG laser beam may also be coupled to and transmitted by a flexible fiber optic quartz cable so that both the coagulating 1.06 micrometer beam and the cutting 1.44 micrometer beam may be transmitted through the same fiberoptic cable.
