Abstract
A compact solid state source of coherent laser light in the range of about 298 nm through about 355 nm utilizes a Nd:YAG or Nd:YLF laser to pump a tunable Ti:Al2 O3 laser. The beam from the Nd:YAG/Nd:YLF laser is then combined in a nonlinear optical crystal with the tunable beam from the Ti:Al2 O3 laser to provide a continuously tunable laser beam in the range of about 298 nm through about 355 nm.
