QD Laser Inc., Laser Device Div.Request Info
 
QD Laser Inc. has introduced the QLD1061, a single-mode distributed feedback (DFB) laser diode emitting in the near-IR wavelength band around 1064 nm. The RoHS-compliant device offers fiber output power of >30 mW, with a stable spectral single mode and a narrow linewidth of <10 MHz. The 14-pin butterfly laser module includes an optical isolator, a monitor photodiode and a thermoelectric cooler and is pigtailed with a polarization-maintaining fiber. It can be used for continuous-wave and pulsed applications such as sensing, frequency doubling, light detection and ranging, and injection seeding for fiber amplifiers or lasers. Forward current is 250 mA, reverse voltage is 2 V, thermoelectric drive current is 2 A, and thermoelectric drive voltage is 4.3 V. Operating temperature is from 0 to 60 °C.
