Activ-Passive mode locking of an Nd:phosphate glass laser pusing #5 saturable dye

An acoustooptic loss modulator and Eastman #5 saturable absorbing dye are used to stably mode lock a TEM
00
Nd:phosphate glass oscillator. This hybrid approach has enabled reliable generation of ∼ 6 ps duration pulses largely free of occurrences of satellite pulse structure.
