Product Overview:

808nm, 4 Watt Fiber Coupled Laser Diode Source with Control System Overview

The LDX-808NM-4W includes a fiber coupled 808 nm, 4 Watt laser diode as well as an all-inclusive control system: precision current source and temperature controller, laser diode mounting plate with the heat sink and cables. This laser module is suitable for applications including material processing, sample illumination, and solid-state laser pumping.

These systems are a convenient, high performance 808 nm multi-mode laser diode source and control solution for research and development in lab environments.

The fiber coupled laser sources are known for their high efficiency and robust thermal design structure. They are designed to yield lifetimes of thousands of hours at full rated power. The 11-pin fiber coupled package laser 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.

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 808nm Laser Diode

The user has complete control of the 4 Watt 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.
