ALS-SFG

Sum frequency generation
The ALS-SFG Series is engineered to push boundaries - combining high power, single-mode, and single-frequency performance with ultra-low noise to deliver the ultimate in precision and stability. Whether you're driving cutting-edge quantum research, interferometry, semiconductor inspection, or laser pumping, ALS-IR provide the clean, stable beam your application demands.
Designed for long-term reliability, the ALS-IR Series features a rugged, all-fiber design with a coolerless laser head that guarantees excellent spatial mode quality. There's no need for alignment, tuning, or maintenance - just seamless, hands-free operation that keeps your system running flawlessly 24/7.
These systems excel in stability, offering best-in-class performance where it matters most: ultra-low relative intensity noise, no added phase noise, outstanding pointing and frequency stability, and the narrow linewidth characteristic of true single-frequency operation. Whether you're advancing fundamental research or scaling industrial innovation, ALS-IR delivers the reliability, performance, and integration simplicity to accelerate your goals -with delivering light you can trust, every time.

Your Benefits

High power up to 10W
With our ALS-SFG mixing platform, you are able to reach very high power at wavelength ranges that are not available from direct IR fiber amplifier platforms. 
Easy combination of any of our IR fiber lasers and amplifiers
The ALS-SFG laserhead elegantly couple light from 2 collimated outputs from our standard IR fiber lasers and amplifiers. 
Compatible with our resonant doubling solutions
The laserhead design has been thought to conveniently match our resonant doubling platforms to reach wavelengths down to 298 nm. 
Industrial grade design, compact and coolerless laserhead
Taking up little valuable table space and running reliably without air or water cooling. 

Applications

Rydberg excitation
Atom laser cooling & trapping
Quantum computing & simulation

SHG pro
You can easiliy and efficiently couple this resonant doubling solution to the laserhead.
Active noise reduction system
The noise eating option ALS-ANRS-YB reduces the intensity noise even further. [100 Hz .. 3 kHz] : <-135 dBc/Hz, [3 kHz .. 10 MHz] : <-150 dBc/Hz, [100 Hz .. 10 MHz] : <0.005% RMS. It must be implemented in a water-cooled rack.
Signal monitoring for locking
The ALS-MONITOR option provides access to the signal for locking purposes. Output interface : 1.2 m long fiber, FC/APC connector.
Remote control interface
The ALS-RCI device enables a full external control of the product via serial commands (UART protocol) or via software.
