1560 nm Fiber Laser

High Power, Low Noise, Polarization Maintaining (PM)

Product Description

The QTekLaser™ 1560 nm Fiber Laser is a high-power, single-frequency PM system delivering up to 20 W with ultra-low noise, narrow linewidth (~10 kHz), and excellent beam quality (M² < 1.1). Housed in a rugged 19-inch 3U rack-mount chassis, it integrates seed and amplifier in an all-fiber, SBS-free design, offering high polarization extinction (>23 dB), >30 dB output isolation, power stability <1%, and reliable water-cooled operation. Featuring IoT-based remote control, safety interlocks, and IEC 60825-1:2014 compliance, it is ready for both research and industrial use. With its coherence, stability, and compact form, the 1560 nm laser is ideal for quantum computing, sensing, laser cooling and trapping, spectroscopy, atomic interferometry, and precision metrology.

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.
