There are numerous applications for laser diffraction. Their key applications include using them as part of a particle sizing technique, and using them in laser diffraction spectroscopy.

Applications of junction lasers are in terms of laser output beams as information carriers. Since this output beam needed to be modulated in terms of intensity, the junction laser is handy. The junction laser supplies regulated current.

They are used to support mobile labeling applications.

Applications of lasers in medicine:

- laser surgery (very, very important in dermatology, ophthalmology, stomatology, otorhinolaryngology, etc.)

- irradiation with laser beams (not serious)

There are many different applications of the Epilog Laser Engraver. When people hear the term laser engraver, they most commonly think of metal engraving. The Epilog Engraver has a wider variety of uses which include, but are not limited to, wood engraving, glass etching and engraving, and fabric cutting.
