December 20, 2005 Bozeman, MT -- ILX Lightwave has added high-power, laser diode current sources to its portfolio of precision laser diode instrumentation products. The company says its LDX-3600 Series current sources are high performance drivers designed specifically for controlling and testing high power laser diodes.

The five products in the series provide currents from 10 amps to 120 amps in CW and QCW modes. According to the company, features such as high setpoint accuracy, low output noise, and 4-wire voltage measurement, combined with an IEEE488/GPIB interface, make the current sources ideal for precision, high power laser diode testing.

A power display mode allows laser diode power to be set based on slope efficiency and threshold current parameters. External output power monitoring is supported through an independent photodiode measurement circuit. Multiple laser diode protection features include adjustable voltage and current limits, output shorting relays, and a high level of immunity to operating and power line transients. In addition, all 3600 series drivers accept a thermistor input for temperature monitoring with programmable temperature limits affording additional laser diode protection. Dual independent interlocks are provided for further laser and operator protection.

The company says the LDX-3600 Series intuitive front panel is designed for quick and easy operation without confusing multi-level menus. Dual displays allow simultaneous indication of laser current, voltage, or power, while simultaneously monitoring temperature. Laser diode current, voltage, and temperature limits along with pulse mode parameters such as pulse width and duty cycle, are set through front panel controls.
