808nm, 80 Watt Turn-Key Laser Diode Source Overview
The LDX-808NM-80W turn-key laser diode source and control system includes a Coherent model 80W-28FF CCP-packaged laser diode bar, pre-configured laser diode controller, heat sink with TEC-cooled laser mounting plate, and cables. This all-inclusive system is a complete plug-and-play solution for R&D applications. The controller is a precision laser diode current source with Peltier/TEC temperature controller for the high power TEC-cooled mounting plate. The control system is optimized for the single bar package and comes pre-tested with the CCP packaged laser prior to shipment.
User has Complete Control of the 808nm Laser Diode
The user has complete control of the 80W Coherent laser through the front panel or through the rear panel RS232 (or optional USB interface). 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. For remote control, LabView drivers are available free of charge charge.
Factory-Configured Laser Diode Protection
High power laser diode protection features include a factory pre-set current limit, slow start current ramp up 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.
Flexible User Controls
Users have full control of the laser module power through a touch-key front panel menu and LCD display or through the digital interface. Laser diode output power level is controlled by directly adjusting the current level. The user also has full control over the laser module temperature. Safety limits can also be adjusted.
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:
The system employs 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 and in a safe operating range.
