ALS-IR series is a range of high power, high brightness Single frequency All Fiber based MOPA Technology infrared laser. We design standard and custom lasers inside wide range of wavelength available from Yb3+ fiber based laser technology. Based on patented technology and major advances in fiber and system design, our fully integrated laser platform offers diffraction limited output powers in excess of 50 W (depending on wavelength).For our standard 50W devices we include in the coolerless laser head a high power IR isolator to prevent damages that may occur from an intense back reflection, therefore the available power is >45W. A full spectral control of the output is possible with linewidths down to less than 50kHz (single longitudinal mode) and a drift of the central wavelength down to less than 0.05pm over several hours.
