Thorlabs, a leading developer of vertically integrated photonics solutions, has released a new ultra-low noise semiconductor laser product line. The lasers (ULN15PT/ ULN15PC) offer an excellent combination of high-output power (>100 mW), narrow linewidth (<100 Hz), and ultra-low relative intensity noise (RIN <-165 dB/Hz). Based on a patented Fiber Bragg Grating (FBG) external cavity design, these lasers provide output centered at 1550 nm.
The ultra-low-noise lasers build on Thorlabs’ class-leading semiconductor gain chip to offer a unique combination of high output power, low phase noise, and low RIN for demanding applications in remote sensing, optical comb generation, and RF/microwave photonics.
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.
According to Paul Morton, CEO & Founder of Morton Photonics, the companies will continue to look forward to the collaboration, such as Morton Photonics supporting wavelength division multiplexing (WDM) as well as extending the product line to other wavelength bands. Thorlabs will provide sensing markets with higher performance, lower cost, and more reliable semiconductor laser solutions and also support emerging applications in atomic physics and quantum information processing.
The ultra-low noise semiconductor lasers join Thorlabs’ extensive offering of single frequency lasers, which span wavelengths from 671 nm to 11 µm.
