ALS-IR Fiber Lasers & Amplifiers
Single frequency CW for your power hungry application
- High power up to 130 W
- Active noise reduction system
- Turnkey, maintenance free, industrial-grade systems
Advanced quantum technology applications demand high performance and high power light sources. Be it gravitational wave detection or quantum computing.
The ALS-IR series is a range of lasers and amplifiers based on innovative fiber technology and represents a real breakthrough on the laser market especially over solid-state technologies. It combines the most stringent fiber laser specifications: high power, single mode, single frequency, ultra-low noise, to enable the most demanding applications.
Our products show ultra-low intensity noise compared to other laser technologies.
As an option, we propose the ANRS (Active Noise Reduction System) that allows an intensity noise reduction of >15 dB in the low frequencies.
The unique all-fibered architecture and the absence of complex cooling systems allows for reliability, robustness and efficient integration in industrial or academic setups.

- Options
The ALS-IR series can be supplied as lasers with the addition of the proper seed laser. Ask us for the best fit for your application.
Rack cooling: Air-cooled or water-cooled. Note that some architecture must be associated with a water-cooled rack
Fibered optical output: Up to 10W of power, the ALS-IR series can be supplied with a fibered output with a FC/APC connector
Active Noise Reduction System: This noise eating option reduces the intensity noise even further (Typically -155dB/Hz between 1 kHz…10MHz). It must be implemented in a water-cooled rack.
Remote Control Interface: This device enables a full remote control of the product via a GUI and a USB connection (read/write). Serial commands are available for integration in a supervision.
