Abstract

The design of an acousto-optic modulator using paratellurite requiring only low driving power is described. Because of the high figure of merit a high modulation index can be achieved. To avoid an intermediate transmission peak the modulator should not be operated in the Bragg-regime but rather in the transition regime. The time dependent transmission for this regime is calculated as a function of the material parameters. Experimentally, modulation indices up to 10 are obtained. Using such a TeO2 mode-locker a pulsed Nd:Cr:GSGG laser delivered pulses down to 70 ps.
