Product Overview:

638nm, 175mW, Laser Module Overview

These high stability 638nm laser diode modules deliver up to 175mW of output power. They are manufactured by RGB Photonics, Germany. These modules are designed for demanding applications that require both high stability and excellent beam quality. They offer user adjustable output power, user adjustable temperature, a USB interface and control software. They can be configured with a free-space output or a fiber coupled output.

These modules connect to your PC through a USB interface and include the GUI based control software. The user interface makes set-up quick and easy.

These laser diode based modules are available with multiple options to optimize the laser for your application. Accessories include a fiber coupler with fiber patch cord, a mechanical shutter and collimating optics.

High Stability through Precision TEC Based Temperature Control and Low Noise Control Electronics

These diode laser modules include an embedded TE cooler which keeps the temperature at a precise set-point. The active temperature control loop ensures very high short and long term stability. The user can adjust the temperature to fine tune the wavelength through the control software. Also, a low noise current source design enables the low noise laser output.

Simple Set-Up and Complete Control using Graphical User Interface / L-Tune Software

All operating parameters can be set, monitored and controlled from your PC using the Ltune laser control software for Windows. A simple to use graphical interface allows you to adjust the laser power and the temperature. Alternatively, the laser can easily be controlled from your own application software. Please request the Operating Manual for a detailed description of the communication protocol.

Small Footprint for Integration into OEM Product or into your R&D Laboratory Set-Up

The design and small footprint are optimized to provide easy integration into OEM systems or into a lab R&D set-up. The PowerBox power supply module is included in the purchase price. It connects directly into the back of the laser head through a d-Sub connector. These lasers have a wide range of options including a mechanical shutter and a fiber coupled output adapter.
