Creators

Description

Beams from a test laser and a reference laser are input to a fibre coupler with their wavefronts accurately parallel. The beams are transmitted to a non-linear detector where an output signal having a frequency which is the difference between the frequencies of the two lasers is produced. The output may be spectrally analyzed. (author)
