Improved Design For Birefringent FilterHighly selective laser tuning achieved without thin plates of questionable optical quality. Improved birefringent filter developed for use with broad-band-emission laser. Provides improved narrow-band operation and wavelength selectivity. New filter design improves traditional design by providing method of increasing wavelength separation between highly transmitted peaks. Such broad-band lasers becoming popular in scientific laboratories and useful in military applications and separation of isotopes.
