Thorlabs releases Ultra-Low-Noise semiconductor lasers

March 10, 2020 – Thorlabs has announced the release of its semiconductor laser product line, which offers a combination of output power (> 100 mW), linewidth (< 100 Hz), relative intensity noise (RIN < -165 dB/Hz). Based on a Fiber Bragg Grating (FBG) external cavity design, these lasers provide output centered at 1550 nm.
 
Commercialized in collaboration with Morton Photonics, Inc., each laser is packaged in an extended 14-pin butterfly housing featuring two thermoelectric cooler elements for precise laser and FBG control and stabilization. Offered in both polarization maintaining and single mode fiber variants, these lasers can be optimized for wavelength tuning by temperature or current depending on the application.
