Low-Noise, Narrow-Linewidth Turnkey Lasers

Thorlabs offers several low-noise turnkey systems with narrow linewidths. Turnkey laser systems at 780, 795, 1310, or 1550 nm central wavelengths are available. Several types are available, including Distributed Feedback (DFB), Distributed Bragg Reflector (DBR), and Ultra-Low-Noise (ULN) Lasers. The ULN laser is a hybrid design that uses a single angled facet gain chip coupled to an exceptionally long fiber Bragg grating and offers linewidths as narrow as 100 Hz.
