| Article about Frequency Stabilization by WLM 08/2007 |
Long-term frequency stabilization of a CW tunable laser
[PDF-Version, 319 kB]
Abstract:
For the first time to our knowledge we experimentally demonstrate an efficient method for the reduction
of long-term radiation line drift in single-frequency cw Ti:sapphire and dye lasers that relies on a fast and
precise wavelengthmeter together with a digital-analog feedback system. Generation line drift of lasers
is reduced approximately by an order of magnitude down to 40 MHz/h, which corresponds to the residual
drift in readings of the wavelengthmeter itself. The implemented automatic frequency control system
allows us to lock the laser generation frequency to a specified absolute value. This approach may be used
in single-frequency lasers of different types (solid-state, fiber, diode, dye lasers, etc.) and allows reduction
by an order of magnitude or more of the long-term generation line drift in lasers that are not equipped
with other systems for long-term stabilization of output radiation frequency. |

| Longterm Stability of the WS Ultimate with Autocalibration 01/2007 |
NEW: WS Ultimate with Autocalibration. A second fiber input provides automatic, continuous calibration with any
wellknown calibration wavelength standard. The measurement counts or time period between calibrations is adjustable.
The picture shows a longterm measurement of a frequency doubled, Iodine stabilized Nd:YAG-laser by a WS Ultimate
with autocalibration. A frequency stabilized HeNe-laser was used as calibration source. The measurement was done
overnight in a laboratory without any air conditioning or temperature stabilization! The stability of the WS
Ultimate was better than +/- 2 MHz for more than 11 hours! |
