ELUXI_CW_Free_Space_Diode_Lasers

The MatchBox Series

The MatchBox Series is a powerful platform, encompassing CW lasers, 4-wavelength diode combiners and Q-Switch nanosecond lasers. It offers simplicity of integration and selection of >150 products within the series.

Control Interface

MatchBox series lasers (2nd edition) feature a Universal Asynchronous Receiver/Transmitter (UART) controller interface. The pinout is explained below - separately for diode and DPSS lasers. A 'breakout box' is used for converting UART into USB or RS232 protocols. The converter chip for USB is 'Silicon Labs CP2102' and for the RS232 it is 'MAX232'.

Software Interface

Laser control softwareThe MatchBox laser control software is used for checking preset parameters, such as the max. laser diode current, target temperatures for TEC1 and TEC2 and actual measured values of these parameters, as well as the load percentage of the Peltier elements. This is very helpful for laser diode age tracking and other troubleshooting actions. Also the software indicates if the laser is working in ACC (Automatic Current Control) or APC (Automatic Power Control) mode.
