Why narrow linewidth laser has better polarization?

In this product, the semiconductor laser is locked in the N (n >: 1) order sideband, and the driving RF signal of the photoelectric modulator is precisely controlled by the frequency synthesizer, so that the sideband frequency is precisely controlled, and the frequency modulation range and frequency modulation speed are expanded by n times. This product can realize the output of linear frequency-modulated laser with C-band linewidth in the order of KHZ and phase-locked narrow-line laser with fixed frequency difference.

Product features:

π low noise, narrow linewidth laser output π fixed frequency difference laser output

π single frequency operation π linear scanning narrow linewidth laser

Application field:

π coherent laser communication π synthetic aperture radar

π hydrophone π atomic physics

π microwave signal generation of π high precision optical sensor
