Acousto-optic Modulators Based on Flexural Acoustic Waves and its Application to Mode-locked Fiber Lasers

Shorts pulse generation by optical cavitation using absorbent and non-absorbent solutions

“…Internal modulation involves directly changing the output state of the laser by a non-linear device [5]. On the other hand, external modulation is carried out by modifying the parameters of the beam leaving the laser cavity using modulators based on acoustic-optic [6], electro-optic [7], interferometric effects [8,9], or by using saturable absorbers [10,11].…”
