The LDX-3100 offers precise low-noise, high-stability current control of laser diodes
when powered by the appropriate external power supply. The LDX-3100 is optimized
to drive laser diodes and LEDs with an output range of 0250mA and a compliance voltage
>5.5V. It provides the flexibility of a mountable circuit board with laboratory-grade
performance and proven laser protection for critical OEM and other space-constrained
applications. The LDX-3100 Laser Diode Driver can be operated in either constant current or constant power mode. In constant current mode, a stable current can be adjusted from an on-board trimpot or through an external control voltage. The output can be modulated up to 2kHz, so its easy to dither the laser current and power. In constant power mode, the photocurrent from the lasers rear-facet monitor is used in a feedback control loop to the laser drive current to maintain stable laser output power, even if the temperature changes. The LDX-3100 Laser Diode Driver can be linked to the LDT-5100 Temperature Controller to form a compact laser controller package. The products can be used together or independently, are based on ILX Lightwaves proven circuit topologies and are pin-compatible with ILX Lightwave instruments, cables, and laser mounts. For specifications on the LDX-3100 Laser Diode Driver, please refer to the LDX-3100 product brochure. |
