1550nm, DFB Single Mode Laser Diode in Pre-Configured Pulse & CW Mode Control and Mount Module:
- 20mW Peak Pulse Output Power
- User Replaceable Laser Diode

Product Overview:

Pre-Configured Pulsed and CW 1550nm DFB Source & Control Module

These pulsed and CW DFB laser source & control modules offer the user a pre-configured, calibrated solution for fast pulse seed and sensing applications. These modules deliver pulse widths as narrow as 1 to 3 nanoseconds (limitation of a DFB source). The butterfly packaged laser diode has been impedance matched to the pulse current PCB in the mounting socket to ensure clean pulse performance with almost no ring or overshoot. To achieve the shortest possible pulses, the customer has the option to request that the butterfly package be soldered into the mounting socket. These modules are designed primarily for pulsed fiber laser, direct frequency conversion and spectroscopy applications which require a narrow spectral bandwidth and high peak power.

Integrated 1550nm DFB Laser Diode Source

The integrated 1550nm laser diode source is a fiber coupled DFB laser. The distributed feedback grating, DFB, located in the laser cavity provides the wavelength stabilization. Both the chip in the butterfly package and the package itself were designed and optimized to provide nanosecond and sub-nanosecond pulses. The coupling of the laser light into the fiber is based on proprietary techniques and manufacturing processes that provide high peak output power. The power is very stable over time and over temperature.

Pulsed Laser Diode Control Electronics and Butterfly Mounting Module

The control electronics and mounting module for these DFB lasers delivers high stability current pulses which can be generated internally by an on-board pulse generator or on demand from an external TTL signal. The external trigger source can be used to trigger the pulse parameters which are preset in the control module. These control modules offer multiple mechanical, thermal and electronic protection features for the DFB source. They ensure that your laser diode is protected and operated safely. The on-board TEC controller incorporates a fast feedback PID control loop to provide high temperature set-point stability. A user-set temperature limit keeps the source from thermal damage. Additionally, multiple bias current / voltage protection features are designed to keep the source safe from ESD, power outages and reverse voltage. A user controlled current limit clamps the current in both Pulsed and CW mode.

USB and Control Software

The user can set and monitor all of the control parameters of the DFB source laser using the USB input and the supplied GUI software. These units ship with the USB cable to connect your PC to the connector on the side panel. A simple to use single page menu graphical user interface allows you to control all of the pulse or CW parameters as well as set current and temperature limits. Other features of these control modules include a daisy chain output, sync output, alarm monitor and back facet monitor output to monitor the DFB laser's power.
