بچه ها معنی beat چی می شه
The slave laser is locked to one sideband of the modulated signal for optical injection locking of the system. The other channel of the light from the master laser is combined with the output of the slave laser and beat at the photodetector. The beat note is mixed with a microwave reference, with the mixing output filtered by a low-pass filter to achieve phase-locking of the wavelength from the master laser
