Product Overview:

1940nm, 10 Watt Turn-Key Laser Diode Source Overview

These 1940nm, 10 Watt source and control systems offer a complete plug and play solution for R&D laboratory applications. These units includes a COHERENT / DILAS conduction cooled single-bar with 19 emitters. This source and control system is comprised of a 10W conduction-cooled single bar laser diode, a 55 Amp current source with 180 Watt temperature controller, a high power TEC cooled heat sink module, and cables. The laser mounting plate comes pre-configured for the DILAS CS package bar mount. The controller is optimized for high power modules and is pre-tested and calibrated with the laser module prior to shipment.

User has Complete Control of the 1940nm Laser Diode

The user has complete control of the 10W laser diode through the front panel or through the rear panel RS232/USB. The user controls the bias current, temperature set-point, CW or modulated mode and several other parameters. The front panel has an LCD display with a touch key-pad. The menu structure is simple to operate, and features a status menu with current and actual temperature for the default home page setting. These systems come with an RS-232 interface and can be ordered with an optional USB interface. LabView drivers are available free of charge charge. A LabView GUI makes set-up and control of the system fast and simple.

Factory-Configured Laser Diode Protection

High power laser diode protection features include a factory pre-set current limit, slow start current ramp to the user specified set point, factory pre-set temperature limits and clamping circuitry to protect the laser against power surges. The factory set default maximum current level is set during the calibration process to ensure the laser is not over-driven and damaged. The temperature limits are determined during calibration and are also factory set within a safe operating range to protect the laser against over-heating. In addition to the current the temperature limit protection settings, the user has the option of setting the soft-start current ramp time from 300 milliseconds up to 10 seconds. The system is set to a 300 millisecond ramp as the default mode. This user adjustable current ramp allows you to customize the "power on" sequence of the source for your specific application.

QCW and Modulation Features

In addition to standard CW mode, these units offer an external modulation input and circuitry and an internal function generator for quasi-CW pulsing applications. The internal function generator is used to generate QCW pulses from 20 μs to CW. The controller will also accept an external signal for the QCW trigger. The modulation can be either TTL or analog modulation from DC to 50 kHz. The modulation input is a BNC connector on the rear panel of the controller.

TEC Based Temperature Control System

These units have an integrated high power TEC temperature controller with a full P.I.D. control loop to deliver fast and efficient heat removal from the source laser module. The laser diode is mounted on a Peltier / TEC cooled, nickel plated copper mounting plate. The mounting plate offers very high surface finish and flatness for low thermal impedance. The cooled mounting plate for the laser is attached to a fan cooled air duct to remove the waste heat and keep the laser temperature stable.

Flexible User Controls

Users have full control of the fiber coupled laser module power through a touch-key front panel menu and LCD display or through the digital interface. You control the high power laser diode amplitude by adjusting the current level. These systems can be controlled remotely by RS232 or optional USB. They ship with LabView drivers and a terminal control software programming suite. All systems have both digital and analog modulation control inputs.
