A dual-mode laser driver that has high current stability, power efficiency and low noise is available from Analog Technologies Inc. The device, for driving high-current diode lasers, can be used to control and monitor laser constant current and power. It features shutdown functions and a control loop stability indicator. The laser driver provides a reference voltage of 2.5 for setting the output current and power or for voltage referencing to analog-to-digital and digital-to-analog converters. The metal package measures 25.4 x 20 x 4.5 mm.
