QLD106L-xx50C series
1m wavelength range 50 mW CW DFB Laser Butterfly Package

C00243-01 November 2020

1. DESCRIPTIONThe QLD106L-xx50C series is a 1m-wavelength range distributed feedback (DFB) laser for use in seeder for fiber
lasers and sensing applications. The laser is assembled into a 14-pin butterfly package with a monitor PD and athermo-electric cooler.
2.

FEATURES• Single longitudinal mode operation• Fiber-pigtailed 14-pin butterfly package with a monitor PD and a TEC• Without an optical isolator and with one polarizer• Polarization maintaining fiber integration• CW operation

3.

APPLICATIONS• Seeder for fiber lasers• Sensing

(*2) Tighter wavelength tolerance is available as an option.
(*3) The spectral linewidth under CW operation is about 10 MHz, but QD Laser cannot guarantee the value because it strongly
depends on measurement conditions including drivers for operations.
