Abstract
An optical blue parametric generation relies upon a nonlinear optical cryl of lithium borate (LiB.sub.3 O.sub.5) properly oriented to generate blue light when appropriately located in a resonant optical cavity and pumped with high intensity light at 355 nm. Beam walk-off and beam pump divergence are greatly reduced due to a specific orientation of non-critical phase-matching so that the 355 nm pump source provides for a sufficient phase-match for output generation near the H Beta Fraunhofer wavelength at 486 nm and also provides for a temperature tuning of the lithium borate crystal to permit exact coincidence to a particular output wavelength so that optical parametric generation from 470 to 487 nm may be assured by the appropriately tuned lithium borate crystal.
