1.5μm Ultra-narrow Linewidth Laser

u Product introduction

The 1.5μm single-frequency ultranarrow linewidth laser manufactured by CSRayzer adopts semiconductor DFB chip, utilizes high Q-factor F-P cavity and volume grating (VBG), realizes linewidth narrowing by self-injection locking, reduces the phase noise of the semiconductor laser, and realizes compact ultra-narrow linewidth output. With the ultra-low noise drive circuit module of CSRayzer, it has the advantages of small package size, lower power consumption and better anti-environmental interference ability.
