The Newport 5060 6.0 Amp Laser Diode Driver delivers precision current control for demanding laser applications requiring stable, low-noise output. Operating from 500 mA to 6.0 Amps with 16-bit control resolution, it maintains better than 50 ppm long-term stability. The driver combines constant current and constant power operating modes with external analog modulation capability (300 kHz high bandwidth, 10 kHz low bandwidth) to support both static and dynamic laser characterization. Multi-layer laser protection—including fully independent current limiting, slow turn-on sequencing with redundant FET and relay shorting circuits, high-speed transient detection, and CDRH compliance—safeguards laser diode integrity throughout operation.
