QLD1X6X Lasers are single-mode DFB lasers with 30 to 60 mW output power for wavelengths from 1020 to 1190nm. The QLD1X6P laser is a high-power DFB with pulsed peak power up to 400mW. These lasers are mounted in a standard 14pin butterfly package with an optical isolator and with a polarization-maintaining optical fiber (PMF). These DFB lasers show excellent single-mode stability and are suitable for both CW and short-pulsed operations. QDLaser is also able to provide a Wavelength Division Multiplexer (WDM) DFB Laser Combs for your specific wavelength window.
