15 Amp High Voltage Driver Overview
The LDC-832 high power laser diode driver offers a maximum output of up to 330 Watts and can operate in constant current CW or pulsed Quasi-CW mode. These units feature a high efficiency design with high reliability components to offer long-life operation, and are integrated into industrial lasers systems used in harsh environments as well as laboratory R&D applications.
Laser Driver Safety Features
These drivers feature a user programmable soft-start ramp of the laser diode bias current. The factory sets the ramp time to 300 milliseconds as the default. This current ramp-up and ramp-down function is designed to protect the laser from thermal shock during power-up and power-down sequences. The LDC-832 has AC line filters and a fast response to shunt the current in the event of an open-circuit. Also included is the ability to control an external cooling fan: a temperature sensor input is available on the back panel, and the external fan control is capable of driving up to 800 mA at 24 V.
CW and Quasi-CW Modes of Operation
In addition to CW (continuous wave) mode of operation, the 823 offers flexible modulation capabilities and an integrated QCW mode. The controller has an internal function generator which can be used to set the modulation signal or the quasi-CW pulses with a time base accuracy of 1.0%. In QCW mode, the user can also set the pulses from a remote TTL signal source. The typical rise time of the QCW mode for these drivers is 25 µs. Faster rise times are available on request. Rise times less than 5 µs are achievable if the load and cabling are optimized for fast pulses.
Laser Driver Control Interface
The LDC-823 features an RS232 interface and includes LabView drivers. An optional USB digital interface is available; inquire for details on ordering the USB control option.
