Product Overview:
Precision 20 Amp Pump Laser Diode Driver
The LDI-187 series driver is an affordable precision current source which offers up to 20 amps and 6 volts of power to bias your laser diode. They have industry leading protection features to make sure that your high power device is not damaged by AC line power surges, over-current, reverse transients and multiple other potential sources of harm to the laser. This model includes an RS-232 digital interface with an option for a USB interface. In addition to the continuous wave (CW) DC current mode of operation, the LDI-187 also includes a Quasi-CW mode with a built-in function generator that can deliver pulses from 25 µs to CW. These drivers are designed with multi-stage filtering to deliver low noise, high stability current to the laser diode.
Designed to Safely Bias 808nm ~ 980nm Single Emitter Pump Laser Diodes
These laser diode drivers were designed specifically for fiber coupled and free-space pump laser diodes from companies such as LUMICS, Lumentum and II-VI. It has a fast feedback analog control loop which detects open circuit conditions and immediately shorts the drive current. The user can set the current soft-start ramp time period or can use the default factory setting of 300 milliseconds. The user programmable soft-start current ramp is designed to allow the user to optimize the ramp time to avoid thermal shock to the laser. Thermal shock can result from quickly ramping the drive current and the subsequent heat generation which occurs before the temperature of the device under test can be stabilized.
Includes Internal Function Generator for QCW
The internal function generator on the LDI-187 provides the user with the flexibility to run the laser in multiple modes such as "hard-pulse" or microsecond pulsing QCW mode. It has a BNC input on the rear panel which allows the user to apply an analog or digital modulation signal which can be used to dither the drive current. Also, sequencing software is available to allow the user to set a string of desired current set-points: the unit auto-sequences through a pre-set range of current points for the pre-set dwell times for each point.
Compatible heat sink options with interface cables are available for most fiber coupled laser package styles. Inquire for details.
