Allows tunable lasers to be used as interferometry sources.

"Lizzie, where did Billy get a tunable laser saw to cut this door with?"

Designs applicable to tunable lasers with beam expansion factors of up to 200 have been disclosed in the literature.

For example, diffraction gratings have been used to create a tunable laser that can tune over 15% of its center wavelength.

A tunable laser is a laser whose wavelength of operation can be altered in a controlled manner.

There are many types and categories of tunable lasers.

The first true broadly tunable laser was the dye laser.

This constituted the first disclosure, in the open literature, of a tunable narrow-linewidth laser tested on a rugged terrain.

In practice, a tunable laser can be used to access an excited intermediate state.

Such research has become possible only with the advent of tunable lasers, which can emit light over a range of wavelengths.
