Generation of time synchronized frequency tunable picosecond light pulses in a mode-locked Nd:glass double laser system

Abstract

An active and passive mode-locked Nd:glass double laser system is built-up. It consists of two gain branches and a common antiresonant ring. The electro-optic Q-switch, the acousto-optic modulator and the saturable absorber are incorporated in the antiresonant ring. A Nd:phosphate glass rod, a Nd:silicate glass rod, and birefringent tuning elements are in the separate gain branches. Time synchronized pulses of 15 ps duration were be tuned over a frequency region of 0 to 200 cm"" 1 ,

“…Laser wavelength tuning across the luminescence linewidth is readily achieved by insertion of a tuning element in the laser oscillator [13][14][15][16].…”
