1590 nm Fiber Laser

High Power, Low Noise, Polarization Maintaining (PM)

Product Description

The QTekLaser™ 1590 nm Fiber Laser is a single-frequency, polarization-maintaining system delivering up to 10 W CW output over the 1580-1600 nm range. Housed in a rugged 19-inch 3U rack-mount chassis with an all-fiber, SBS-free design, it features narrow linewidth, excellent beam quality, high polarization extinction ratio, low thermal lensing, and power stability under 1%. Controlled via an IoT/TCP interface, it includes safety interlocks and complies with IEC 60825-1:2014. Ideal for demanding applications such as quantum computing and sensing, atomic interferometry, laser cooling/trapping, and precision research.

Single Frequency

QTekLaserTM amplifiers work with various kinds of seed lasers. They can be economic semiconductor diode lasers with MHz laser linewidth, robust fiber lasers with kHz linewidth, or cavity-locked ultra-stable lasers with Hz linewidth. Based on customer requirements, we can recommend the best options and integrate them into the laser system as illustrated in figure 1.

QTekLaserTM lasers comply with Federal Regulations (21 CFR Subchapter J, Part 1040)  as administered by the Center for Devices and Radiological Health and are certified to IEC 60825-1:2014 standards.

It is the end user's responsibility to ensure that no significant light is retroreflected back into QTekLaserTM systems as this can degrade performance and potentially damage the lasers. To prevent this, the use of an external optical isolator is strongly recommended.  Damage due to retroreflected light is not covered under warranty.
