Electrooptic ceramics as wavelength selection devices in dye lasers

The output center wavelength of a rhodamine 6G dye laser was tuned by using variable birefringence filters in the cavity. The electrooptic properties of two different lead lanthanum zirconate titanate (PLZT) ceramics were used in these filters to achieve up to 120 Å of wavelength tuning. Spectral bandwidths varied from 20 to 120 Å with these particular filters.
