Khokhlov suggested the possibility of a smooth change in the frequency of lasers by methods of nonlinear optics.

The medium can change the light of the beam, and ...

... and hence the frequency.

Experience: The laser emits an invisible infrared beam.

Put a crystal in its path and the beam becomes visible.

It's not easy.
