The New Focus 6437 Vidia-Discrete laser is a stable, narrow-linewidth source of tunable light. The laser operates in three modes: track mode, automated stepscan mode, and interactive step-scan mode. Use it in track mode to operate it at a set wavelength. In the step-scan modes, the laser dwells at evenly spaced wavelengths as it scans. The system can be operated manually, using the front-panel controls, or remotely, using one of the computer interfaces. The 64X7 Series Vidia-Discrete laser is an external-cavity diode laser (ECDL) based on the Littman-Metcalf design. The system provides high resolution when stepping between wavelengths. An ultra-low-noise current source controls the laser’s output power. A temperature-control circuit actively stabilizes the laser-cavity temperature for optimal performance.
