Paper Abstract

A very small form-factor ultraviolet (UV) light source is being developed for military and industrial applications. A miniature UV laser source using multi-wavelength Quasi-Phase- Matched QPM technique utilizing optical non-linear crystals such as Lithium Niobate (LN), Lithium Tantalate (LT), and Magnesium Oxide doped LN and LT (MgO:LN and MgO:LT), KTP crystals is being developed as a part of solution to meet small form-factor. The UV source consists of thermo-electric cooler, heat-sink carrier on which two focusing lens-arrays, array of non-linear crystals are mounted. The light source used for this purpose is 808 nm which generates 1064 nm light after passing through the Nd:YVO4 crystal. The 1064 nm light enters through lens to make incident on to a PPLT or PPLN crystal generating the third harmonic generation output of 355 nm. Simulations show how an average power of 1.0 Watt with a small form factor is achieved. Simulation modeling demonstrates that the third harmonic grating for PPLN devices allowing an overall prediction of expected output efficiency. Simulations show the affect of process variation, excitation frequency variation, and temperature affects power output.
