LDI-800

1.0 and 2.0 Amp. Laser Diode Drivers

The LDI-800 laser diode driver is a general purpose laboratory power supply and laser diode driver useful for any cw laser diode. Designed specifically for safe and fault-free operation of laser diodes, the LDI-800 includes transient suppression and diode protective circuits, a feedback amplifier, set-up mode with a dummy load, overcurrent limit, and full TE cooler control.

The driver provides 3.5 digit display of six key operating functions, and requires operator command for laser turn-on. Embedded microprocessor based logic prohibits illegal commands, while highly stabilized analog circuits provide final laser diode drive.

The thermoelectric cooler controller operates the TEC option on the SDL-2350 Series laser diodes. It may also be used with Peltier elements up to 1.5A and 3V, and 10k thermistor.

The LDI-800M is a high current version of the model LDI-800 driver. It provides nearly 2 amps of diode operating current and includes many of the operating features of the LDI-800. It was designed to power laser diodes such as the 1.2W SDL-2360 Series.

The LDI-800M supplies transient-free and stable electrical power. It does not include TE cooling capability, a feature provided in the LDI-800. Devices requiring temperature stabilization may be thermally controlled with a separate TE cooler driver and temperature sensor, or by either the LDI-800 or LDI-820.

These drivers meet the requirements of 21 CFR 1040.10 laser safety regulations.
