Product Overview:
LDI-726 High Power Laser Driver Overview
The LDI-726 driver offers 30 Volts compliance voltage at 20 Amps for laser diodes connected in series, laser diode stacks and multi-emitter devices. On request, the current and voltage can be configured to match any customer specified range with a total of 600 Watts of output power to the laser. The LDI-726 was designed with features to protect expensive multi-emitter pumps, and are used to safely bias 8XX through 9XXnm pumps with output power levels from 20 Watts to 300 Watts from companies such as Lumentum and II-VI laser.
Laser Diode Protection Features
To ensure that the series connected array of diode lasers is not damaged or destroyed, the LDI-726 offers voltage transient protection and voltage clamping circuitry in addition to a user-set current limit. In addition to the current and TEC limits, there is an interlock safety connection as well as a front panel Emergency-Stop kill switch to ensure safe operation of the laser.
The LDI-726 offers the industries only user-set slow-start current ramp to the bias set point. This allows the user to extend the ramp time out to 10’s of seconds to prevent the possibility of thermal shock and prevent over driving the module during the start up sequence. These units ship with a default 300 milliseconds current ramp.
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 500 mA at 24 V.
CW- and Quasi-CW Modes of Operation
In addition to CW (continuous wave) mode of operation, the LDI-726 offers flexible modulation capabilities and an integrated QCW mode. The user can apply a TTL digital or analog modulation input through the rear panel BNC. 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.
User Interface and Cable Connectors:
Controller setup is fast and intuitive via the front panel LCD display and alphanumeric interface, with a simple to use menu structure and key pad.
The controller employs a high-current two-pin connector, type DSUB-2W2, for connection to the high-power laser diode module.
These systems come with standard an RS-232 interface. The included LabView driver GUI makes set-up and control of the system fast and simple. The controller can be ordered with a USB interface; contact us for more information.
