940nm, 10 Watt Turn-Key Laser Diode Source Overview
The LDX-940NM-10W is a multimode pump laser diode source and control system. It is a pre-configured system which includes the fiber-coupled laser, the controller, the mounting plate/heat sink and all cables. These systems are also available at 915nm and 975nm center wavelengths. This fully configured system includes the laser diode and is optimized for powering and controlling high power single emitter pump lasers.
User has Complete Control of the 940nm 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 all other key 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.
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.
Fully Configured Temperature Stabilized Mount and Heat Sink
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 mounting hole footprint pattern is pre-configured for the Lumentum L4 and L4i package style 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 or adjusting the laser in automatic power (APC) control mode (Watts of optical power) based on the internal monitor photodiode feedback to the bias current and temperature controller. These systems can be controlled remotely by RS232 or USB. They ship with LabView drivers and a terminal control software programming suite. All systems have both digital and analog modulation control inputs.
