ABSTRACT:
Apparatus for providing beams of laser radiation at wavelengths of 1.44 .mu.m and 1.064 .mu.m on demand. Two Nd:YAG lasers are arranged in a side-by-side configuration and operated to provide laser output at wavelengths of 1.44 .mu.m and 1.064 .mu.m, respectively. In the preferred embodiment, a reflective spectral filter comprised of two reflectors reduces the amount of 1.064 .mu.m radiation in the output beam from the 1.44 .mu.m laser by a factor of 100 to 1000, but only reduces the amount of 1.44 .mu.m radiation in the output beam from the laser by less than 2%. The apparatus also provides collinear addition of the output from the 1.064 .mu.m laser. This collinear addition enables output radiation from both lasers to be coupled together into a single optical fiber. In fact, a user can choose to operate either laser separately or to operate both lasers simultaneously.
