Wavelength Stabilized 1030 nm High Power Mini-Butterfly DFB Laser Diode Module
The Coherent CMDFB10xxA wavelength stabilized high power single mode laser module has been designed as a light source for pulsed narrow bandwidth fiber laser and direct frequency conversion applications. A distributed feedback grating (DFB) located in the laser cavity results in the wavelength stabilization within couple of round trips. The laser chip and package are optimized for subnanosecond pulse operation. Processes and techniques of coupling the fiber to the laser allow high peak output powers that are very stable with both time and temperature.
Applications
- Fiber laser systems
- Frequency conversion

Notes:
1. Conditions unless otherwise stated: Case temperature -20 to +75°C Submount temperature 25°C, CW operation"
2. Also for current pulses >200 ns
3. ~100 ps is achievable in gain switching regime with dedicated pulse driver
4. Tested and guaranteed only at 1.5 ns pulse width, 300 kHz repetition rate, no bias
5. Small signal equivalent circuit parameters for laser chip
6. The absolute maximum ratings are conditions for which the device is expected to recover fully the specified performance. Exceeding these limits may impair the device reliability. The ratings apply to each parameter in isolation; that is when all other parameter have values within the relevant characteristics. It cannot be assumed that limiting values of more than one parameter may be applied to a device at the same time.
