The Stradus™ Family presently contains two direct diode, TEM₀₀  lasers in the red wavelength spectrum (660nm and 642nm). The 642nm version can output power up to 110mW while the 660nm version is capable of 100mW output. The same advantages with the elimination of contaminants and superb power stability that was touted for the blues and violet lasers are also present here for the red lasers.

The Stradus™ 660 and Stradus™ 642 exhibit the highest power, single mode red laser beams currently available in the industry. The red laser, also, can be operated manually by merely bringing the 12 volt DC power to the miniature D-connector on the Stradus™ . The red lasers, also, could be operated normally by hooking up the Remote Control Box (supplied with each standard Stradus™) to the Stradus™. The Remote Control Box allows for the CDRH Safety features (keyed lock switch for on/off), interlock connections, as well as external emissions indicator LED. A user can hook a PC up to the RS-232 connector on the Remote Control Box, or hook up a PC directly to the Stradus™ via a USB cable to the USB Connector on the Stradus™ (see drawing below).

The user, through the use of any PC, can interface to the Stradus™ through the user interface software that is supplied with each standard Stradus™ Laser. The user interface allows for easy and efficient control of all laser functions as well as an effective monitoring display of key laser parameters (e.g., laser power and diode current and temperature).
