Single Frequency Lasers
-
A single-frequency laser is a type of laser which operates within a singular resonator mode, achievable when the net gain bandwidth of the laser remains narrower than the frequency spacing of the resonator modes. In cases where the mode spacing isn’t adequately large to support a single resonator mode, single-frequency operation is maintained through the utilization of intracavity filters. This enables the single-frequency laser to possess an exceedingly narrow linewidth, frequently measuring only a few kHz, and an extended coherent length. A clear association exists between the coherence length and the spectral width of the laser.

Frequency Converter Unit
FCU
-
The Astronics Frequency Converter Unit (FCU) provides frequency conversion of variable frequency aircraft power. Recent trends in aircraft power systems use variable frequency (VF) generators instead of fixed frequency of 400Hz. While the majority of aircraft loads can use VF power, select loads still exclusively require 400Hz and are best addressed by the use of FCUs. The FCU performs the task of converting the power line frequency by leveraging recent advances in solid-state technology to provide dramatic improvements in performance over traditional frequency converter solutions.
