title: Birefringent tuning double frequency He-Ne laser.
abstract: Experimental details are given of a novel, promising kind of double frequency laser-with power output of 0.8-1.4 mW, large frequency difference from 37 MHz to a longitudinal mode interval, and frequency stability of 10(-5), and its potential uses are discussed.
