Advanced Product Announcement
Diode-Based External Cavity Laser
Low Noise
Wavelength: 1561.7 nm
Narrow Linewidth: 2.85 kHz
Product Description
QTekLaserTM products with model No. QT-SF-AMP-xx-xxxx-x-x-xxx-x are a series of fiber amplifier products, amplifying narrow-linewidth (<20 kHz) single-frequency laser light with max output power from 0.5 W to 100 W. A smart internet-of-things (IoT)-based control system is integrated to enhance a user-friendly interface. The system is packaged in a typical industrial 19’’ 3U or 4U rack-mountable chassis.

Specifications
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.
