Paper Abstract

In the present work, a new approach to long-term stabilisation of radiation frequency generated by single-frequency lasers has been experimentally demonstrated. The essence of this approach is in the use of high-precision radiation wavelength meter as a spectral reference. For the first time the method was experimentally demonstrated for reduction of long-term radiation line drift of single-frequency CW Ti:Sapphire / Dye lasers. Generation line drift of lasers was reduced approximately by an order of magnitude down to 40 MHz/hour, which corresponds to the residual drift in readings of the wavelength meter itself. The implemented automatic frequency control system allows to locks the laser generation frequency to a specified absolute value. This approach may be used in single-frequency lasers of different types (solid-state, fibre, diode, dye lasers, etc.) and allows reduction by an order of magnitude or more of the long-term generation line drift in lasers which are not equipped with other systems for long-term stabilisation of output radiation frequency.
