ABSTRACT:
A laser system provides output wavelengths at near 1.06 and near 1.44 micron from an Nd:YAG gain medium, along with a frequency doubled output of the 1.06 micron line. This system is based on a laser resonator with a plurality of turning mirrors, each transmissive at a selective subset of the characteristic wavelengths of Nd:YAG and reflective at a selected output wavelength. The mechanism is coupled with the turning mirrors for selectively positioning one of the plurality of turning mirrors in the optical path, directing the beam on an output coupler having a fixed position with respect to a string of components for delivering the output beam to a surgical site. Also, the mechanism can selectively remove the turning mirror from the optical path. In this case, the beam is supplied to a frequency doubling alternate resonator design and output at the second harmonic of the 1.06 micron line is generated.
