How to cite the article; suggest additional literature

This article deals with lasers emitting in the blue and violet spectral region, i.e., with a wavelength roughly around 400–500 nm. The choice of laser gain media for such wavelengths is limited, and the achievable performance is typically not as good as in, e.g., the infrared spectral region.

Types of Blue Lasers

The following types of blue lasers are the most common:

For wavelengths below ≈ 400 nm, the eye's sensitivity (i.e. its ability to detect small light levels) sharply declines, and one enters the region of ultraviolet light. (See also the article on ultraviolet lasers.) Note that even for wavelengths around or slightly above 400 nm, the retina can be damaged via photochemical effects even for intensity levels which are not perceived as very bright.

Applications of Blue and Violet Lasers

Blue and violet lasers are used e.g. in interferometers, for laser printing (e.g. exposure of printing plates) and digital photofinishing, data recording (Blu-ray Disc, holographic memory), in laser microscopy, in laser projection displays (as part of RGB sources), in flow cytometry, and for spectroscopic measurements. Data recording appears to be the major driver for the development of blue laser diodes. In most cases, the use of blue and violet lasers is motivated by the relatively short wavelengths, which allows for strong focusing or resolving very fine structures in imaging applications.
