14Pin Butterfly Packaged DFB Laser Temperature and Current Driver Mounting Module


DFB butterfly packaged lasers are widely used in many near-infrared TDLAS gas detection. In order to achieve high precision gas detection, we need to control the temperature and current of DFB lasers precisely. The high performance driver module DFBM1550 developed by Idealphotonics independently, is specially designed for 14pin Butterfly Packaged Laser Diodes. DFBM1550 module integrates not only radiating unit, but also the temperature control circuit and low noise current driver. The driver has ultra-low current noise and it has no ripple or overshoot. It contains 2 modes including local and remote. It also supports external analog modulation and multiple state monitoring ports. It is well adapted for near-infrared TDLAS detect system integration and OEM applications.
The special design of maximum soft current clamping function, can avoid large current damaging the laser diode in emergency conditions. You can build a near-infrared TDLAS detect module by using this module, Idealphotonics InGaAs detector unit and Idealphotonics’s phase-locked demodulator.
