Spectra Diode Labs SDL-820

The LDI-820 is a high current general purpose laboratory laser diode driver. CW or quasi-cw laser diodes, LED's or similar devices requiring up to 10 amps drive current maybe safely operated and controlled with the LDI-820. Optical power or current control mode, transient suppression, diode protection circuits, set-up mode, overcurrent limit and full thermoelectric cooler control are provided.

The driver features multi-character alpha-numeric display of all key operating functions,error messages, and automatic self-test. Operator command is required for laser turn on. Embedded microprocessor based logic prohibits illegal commands and prevents inadvertent faulty set-up. Highly stabilized analog circuits provide final laser drive. A unique single knob control is combined with function switches for setting of operating
parameters. The lighted alpha-numeric display allows observation of function and
value. The single large control knob permits easy operator interface, even in darkened
laboratory environments and the analog "feel" so useful in fine adjustments.
An internal pulse generator allows operation of quasi-cw devices or digital modulation
of cw laser diodes. External triggering, and external modulation inputs are provided.

The thermoelectric cooler controller operates the TEC option on all SDL laser diodes, or may be used to control external TEC devices.
This controller is calibrated for use with 10 kΩ thermistors and provides up to 5A at 10V.

This driver meets the requirements of 21 CFR 1040.10 laser safety regulations.
