BASICP ROPERTIES OF LBO RELATEDTO HIGH EFFICIENCY FREQUENCY CONVERSION OF BROADBAND LASER

In thispaper, the phase matching angles in LBO at l.054um have been studied for all sorts of doubling and tripling through the Sellmeier equation. The spectral acceptance and the angular acceptance are analysised emphatically.It's first shown that high efficient third-harmonic frequency conversion of broadband high-power Nd: glass laser using LBO crystal can be attained by well-developed techniques.
