HIGH POWER INFRARED SINGLE MODE OPTICAL PM FIBER AMPLIFIERS up to 50W in IR

ALS-IR-AMP series are design to provide solutions in the atom cooling domain when specific narrow spetral line width are needed.

Azur Light Systems opens the available solutions either providing the full laser source or only the high power optical stage amplifier.

Most common central wavelengths:

 bouton amp 1030 sombre bouton amp 1040 sombre bouton amp 1050 sombre bouton amp 1064 sombre

 

Almost all the central wavelenghts are available from 1020 nm to 1090 nm, only the max output power may change below 1020 nm and above 1090 nm

 

ALS-IR-AMP series is a range of high power, high brightness Single frequency All Fiber based MOPA Technology infrared laser amplifiers. We design standard and custom optical laser amplifier inside the wide range of wavelength available from Yb3+ fiber based laser technology.

50WS IR fiber laser ld

Based on patented technology and major advances in fiber and system design, our fully integrated laser amplifier platform offers diffraction limited output powers in excess of 50 W (depending on central wavelength).

Our unique technology can power up CW Laser seed optical wave without degrading spectral line width even for ultra narrow line width <1kHz. without line broadening

The optical laser seed input FC/APC request only 15mW (for weaker signal contact us)

A full spectral control of the output is possible with linewidths down to less than 1kHz (single longitudinal mode) and a drift of the central wavelength is only laser seed dependant.

The free space coolerless output head deliver the amplified optical light wave without additional noise. Our low noise technology has demonstrated that the output RIN profile is equal or better than the laser seed noise profile.

Power sharing over several output ports (2, 4, 8, 16...) is available as an option.
