7.4um low power consumption table DFB-QCL Laser is a tunable CW laser developed by LD-PD Inc.The Wavelength tuning range can up to 30nm, Collimation output power more than 10mW.
This module can solve problems in areas such as Gas Sensing.Our DFB-QCL Laser module integrated temperature control, drive.We also build in our Lockin amplifier inside.This Software can also be used to control the working temperature and current of the laser, so that the laser can work steadily and maintain the accuracy of the measurement results.The FPGA is added inside the laser module to facilitate the processing of gas concentration measurement.1f and 2f signal output is possible from BNC Interface and The gain value is optional for our customer.
