In a joint development, ALPhANOV and Muquans have developed an innovative frequency-doubling module that can generate, with outstanding efficiency, several watts in regions of the visible spectrum previously difficult to reach.

This compact module allows energy-efficient generation of several Watts of optical power, with both remarkable output beam quality and high optical stability. It thus paves the way for the use of high-performance laser emission of several Watts for on-site or on-board applications.


The module offers an attractive way to get more than 5 W of optical power over the range [765 nm; 805 nm] with more than 70 % conversion efficiency (other wavelengths are also available). It is dedicated to quantum technology set-ups, remote sensing (LIDARs…) and biology.


Muquans and ALPhANOV worked out an original and patented technology in order to achieve such conversion efficiency whatever the input power level, with excellent optical quality. Fast tunability of few hundreds of MHz is available, and a robust and active stabilization scheme provides excellent stability.


Although this innovative frequency-doubling module is commercialized by Muquans as a standalone device, Muquans can also provide an entire laser system in a fully integrated rack, including a high-performance seed laser and an amplification stage, the frequency-doubling unit, and dedicated ultra-low noise electronics. It thus offers a complete turnkey solution. ALPhANOV can also offer the development of custom modules.
