It is shown that a birefringent Fabry-Perot etalon, which has a simple configuration similar to Lyot's filter except for mirror coatings on the end-faces of birefringent crystal, is useful for tuning of dye lasers because of the high finesse realized by two stages of commonly used Fabry-Perot etalons. Experimental tuning characteristics of PbMoO(4) and LiNbO(3) birefringent Fabry-Perot etalons in a pulsed dye laser, pumped by the second harmonic of a repetitively Q-switched Nd:YAG laser, are in agreement with the theory.
