Buying Single-frequency Lasers
Single-frequency lasers produce light with a very narrow linewidth, suitable for applications requiring high frequency stability and no mode hops. They are used in interferometry, laser spectroscopy, and optical communications. High-power single-frequency lasers are also employed in coherent beam combining techniques.
