HIGH-CURRENT LASER DIODE DRIVER
Oct 1999Coherent Inc.Request Info
A quasi-continuous-wave laser diode driver available from Coherent Inc., Semiconductor Group, is designed to drive laser diode bars and stacks at high average powers. The air-cooled driver delivers a peak output current up to 250 A with compliance voltage up to 80 V and an average power to 2.4 kW. Pulse length and period, current, duty cycle and compliance voltage can be adjusted with either a front-panel, RS-232 interface or an external transistor-transistor logic gate. A flexible output cable with connectors delivers the current, and the device has built-in overload, laser-diode current and voltage protection. The driver is suitable for laser diode characterization, burn-in and embedded applications.
