| NEW: High Definition Spectrum Analyser - HDSA |
 The » High Definition Spectrum Analyser is designed to analyse emission spectra of any complexity, while processing the entire spectral range from 400 nm to 900 nm at once. The fundamental principle of
HighFinesse products "no moving optics" applies to the HDSA as well, so cw- and pulsed
light sources can be measured.

| Article about Frequency Stabilization by WLM |
| » Long-term frequency stabilization of a CW tunable laser [PDF, 0 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 |
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! |
