ALL-IN-ONE / 1.5 Amp Hybrid Laser Diode Driver, TEC Controller & Butterfly Mount Module (TYPE-1)

Product Overview:

Hybrid Laser Diode Driver + TEC Controller + Butterfly Mount | Integrated Laser Diode Control Electronics and Mount Module
The SF8150-ZIF14 hybrid laser diode control electronics and mounting modules offer an all-inclusive, high performance solution for controlling butterfly packaged laser diodes. These controllers are an excellent choice for integration into a laser system product or as an affordable solution for laboratory test set-ups. Key features of these modules include a low noise laser diode current source to safely electrically bias your laser diode, an integrated TEC / temperature controller and a 14-pin butterfly package mount. They also include multiple control interface options to enable you to control all of the parameters of your laser diode. Interfaces include on-board potentiometers, an RS232 interface, a USB interface and an analog control signals connector.

User Interface:
- On-Board Trim Potentiometers
- USB and RS232, Control Software GUI / Virtual Front Panel Included
- Analog Signal Controls

4-LEVEL LASER DIODE PROTECTION:

1. User Adjustable Current and Temperature Limits
The user can set current limit and temperature limits through on-board potentiometers, or through the software supplied with the SF8000. Also, limits can be set using the analog control signals input. Setting limits are necessities to ensure safe operation and a long life-time for your laser diode.

2. ESD Protection and Power Surge Protection Circuit
An integrated crowbar circuit protects the laser diode from power surges, ESD, and damage to the laser diode from brown-out or black-out events. An integrated on-board zener diode in parallel with the bias current path protects the laser diode from damage which can occur from reverse voltage transients. These transients can occur when a standard DC power supply source is momentarily interrupted due to a black-out or brown-out power outage. Additionally, these module ship with a jumper clip that shunts the laser diode bias current path of the driver to protect the laser from ESD or static discharge when the user is installing the laser into the mounting socket. This shunt also protects the laser when the user is connecting the DC power or any other external equipment.

3. Soft-Start Current Ramp
There is an internal 500 millisecond soft-start ramp to the current set-point. This reduces the potential for thermal shock to the laser at power ON and is used to ensure good electrical contact prior to fully applying the current bias the laser diode.

4. External Over-Temperature Monitor Input
Primarily designed for integration of the module into a laser system, an additional thermistor input is provided to allow the user to monitor the temperature from an external measurement point. This can then be used to shut the laser diode off if a temperature maximum for the system is exceeded.

All-Inclusive Laser Diode Control Solution
These modules are a small footprint driver and mount solution. Careful selection of components and and exacting design criteria allows the modules to provide complete control of your laser in a 61mm x 101mm package. They have a 10mm thick aluminum base plate which provides excellent heat dissipation and keeps the laser diode safely operating within your desired operating temperature range. The module base plate comes with 4 mounting through-holes, 3.2mm each, to bolt the module directly to an instrument chassis or any thermally conductive surface.
