Product Overview:

375nm, 150mW Fiber Coupled Laser Diode Source with Control System Overview

The LDX-375NM-150MW includes a fiber coupled 375 nm, 150 mW laser diode installed and tested in an all-inclusive control system: the control system includes a precision current source and temperature controller, laser diode mount with the heat sink and all interconnect cables. These systems are a convenient, high performance 375nm system for R&D applications in lab environments.

The fiber-coupled 375nm sources are offer high efficiency and robust thermal design structure. They are designed to yield lifetimes of thousands of hours at full rated power. The fiber-coupled HHL package is mounted to the pre-configured heat sink for highly stable thermal control using a 10K Ohm thermistor and TEC cooler to provide active heat control of the package. The laser features an SMA905 detachable fiber connector which is designed for 105µm multimode UV fiber patch cable.

Modulation and Internal Function Generator Features

In addition to standard DC continuous wave mode of operation, these units offer an external modulation input and circuitry. They will accept either TTL or analog modulation from DC to 25 kHz. The modulation input is a BNC connector on the rear panel of the controller. The controller also includes an internal function generator which can be used to generate the modulation signal or QCW pulses from 20 μs to CW. The user has the option of using the internal function generator or triggering from an external generator.

User has Complete Control of the 375nm Laser Diode

The user has complete control of the 150mW laser diode through the front panel or through the rear panel RS232 interface (optional USB is available; please inquire). The user controls the bias current, temperature set-point, CW or modulated mode and several other parameters. The front panel has an LCD display with a touch key-pad. The menu structure is simple to operate, and features a status menu with current and actual temperature for the default home page setting.
