| Abstract: | Fiber lasers are widely used in the military and communications fields, the fiber acousto optic modulator driver as an important part of the fiber laser, has an important impact on the performance parameters of laser quality. This paper presents a high frequency, high power driver solution. The binary amplitude shift keying (2ASK) modulations of the pulse signals and 150 MHz carrier signals are realized through controlling the analog switches of the 20~200 kHz pulse signals, then, the modulated signals are amplified by the power amplifier, and outputs to the acousto optic modulator after impedance matching for driving the acousto optic modulator to work.The frequency of driving signal is 20~200 kHz, and its power is 3 W. |
| Keywords: | fiber acousto optic modulator drive 2ASK modulation power amplification high frequency |
