The Melles Griot 06DLD201 is a precision diode laser driver that delivers stable current and temperature control for laser diode applications. It operates in both constant-current and constant-power modes, offering adjustable current limiting across its full 200 mA range for comprehensive diode protection. The driver supports analog modulation up to 100 kHz and maintains exceptional stability with drift below 20 ppm over 1 hour at 25°C. Housed in a compact 132 mm × 66 mm × 183 mm enclosure, it accommodates most visible and near-infrared laser diodes and suits both laboratory environments and OEM system integration.
