“…3 -3.3-Mm region are described. The present work is closely related to a previous paper 10 on a computer-controlled color center laser and builds on that work. New to this work is the introduction of automatic and semiautomatic calibration methods and the various kinds of feedback necessary to provide long range continuous scans.…”

The conversion of a commercial color center laser (Burleigh FCL-20) into a computer-controlled high resolution laser spectrometer is described. The techniques and methods developed are generally useful for the control of any broadly tunable cw laser. Superposition of several kinds of computer-controlled feedback upon a table look-up (feed-forward) procedure is used for each of the control elements. This feedback removes the coupling between the tuning elements and eliminates the effects of the nonideal properties of the control elements such as PZT hysteresis and creep. The resulting spectrometer is capable of acquiring high resolution (instrumentally limited by free running laser jitter to ~3 MHz) spectra which can be precisely measured (~0.0003 cm(-1)). The spectrometer has routinely made continuous single-mode scans of 30,000 points separated by 10 MHz covering 10 cm(-1).

“…The possibility to detune automatically the output wavelength of the tuneable laser allows full automation of spectral analysis or spectral measurement procedures [1][2][3][4]. In their simplest configuration, such auto-scanned lasers have electromechanically driven selective element that provides control over the laser output wavelength through electronic signals.…”

We present developed computer-controlled tuneable laser system based on CW narrow-line Ti:Sapphire/Dye laser which is meant for laser-optical characterisation of quantum dot properties. The full set of laser system options allows it to cover a spectral range from 275 to 1100 nm while having the output line width around 0.5-1 GHz. The system includes a built-in high-precision radiation wavelength meter and a system of automatic control over the spectrally selective laser elements, thus providing the possibility to automatically set the output radiation wavelength to the absolute precision of 1 GHz (0.004 meV) and to perform continuous scanning of the output radiation line in a specified spectral range.

“…Colour centre lasers were operated c.w. by Mollenauer & Olson (1974) several years before fine tuning control (Litfin et al 1980) permitted their application to high-resolution spectroscopy. The vibronic lasers, which operate in the near infrared on vibronically broadened d-levels in divalent [ 15 ] Vol.…”
