Abstract

A process and apparatus are disclosed for producing multiwavelength coherent radiations ranging from deep-ultraviolet to mid-infrared. The basic laser 1 is a pulsed Nd:YAG or Nd:YLF laser which is frequency converted by a set of novel nonlinear crystals, including D-CDA, LBO, BBO, KTP, and KNbO3, where efficient schemes using noncritical phase matching and cylindrical focusing are employed. A
computer controlled integrated system (Figs. 4 & 5) suitable for multiple industrial and medical applications is described, particularly where a UV (at 210 nm and 213 nm) solid state laser is desired such as in refractive surgery. Furthermore, using optical parametric oscillation and nonlinear crystals, the laser system can produce tunable (1.5 - 4.5 microns) wavelengths covering a variety of medical applications.
