Abstract

A multiline spectrum is imposed by intrinsic birefringence in the laser emission of a prism tuned Ti:Sapphire laser, pumped by flashlamp. With certain polarization alignments, the broadband obtained with a tuning prism in the hemispherical cavity is split into 10-20 equally spaced lines of less then 0.05 nm each. The effect, with potential multiline multiplexing applications, is crucial in laser alignment, with implications in Brewster cut crystal processing. The effect produced by the intrinsic birefringence in Ti:Sapphire crystal combined with the polarization introduced by the dispersion prism in the cavity, is explained and calculated for different experimental cases. For specific applications, one may design the multiline spectral separation and the total number of lines of a specific Ti:Sapphire laser. These parameters can be set to permit tunability over a certain range.
