Laser types with distinct laser lines are shown above the wavelength bar, while below are shown lasers that can emit in a wavelength range. The height of the lines and bars gives an indication of the maximal power/pulse energy commercially available, while the color codifies the type of laser material (see the figure description for details).
The data and its references can be found in the spreadsheet Commercial laser lines.xls (unfortunately Wikipedia does not allow uploading spreadsheets). Currently most of the data is taken from Weber's book Handbook of laser wavelengths [1], with newer data in particular for semiconductor lasers. For quasi-cw lasers (e.g. metal vapor lasers) the ...
The scale numbers range from LB1 to LB10, where the number is a lower limit for the optical density, i.e. LBn means that OD > n, or <, where T is the transmittance. The minimum scale number for a given laser with a beam diameter of 1 mm depends on the working mode and the wavelength as follows (EN 207:2017):
Longer-wavelength radiation such as visible light is nonionizing; the photons do not have sufficient energy to ionize atoms. Throughout most of the electromagnetic spectrum, spectroscopy can be used to separate waves of different frequencies, so that the intensity of the radiation can be measured as a function of frequency or wavelength.
The energy is typically supplied as an electric current or as light at a different wavelength. Pump light may be provided by a flash lamp or by another laser. The most common type of laser uses feedback from an optical cavity—a pair of mirrors on either end of the gain medium. Light bounces back and forth between the mirrors, passing through ...
[5] [6] [7] The spectrum does not contain all the colors that the human visual system can distinguish. Unsaturated colors such as pink, or purple variations like magenta, for example, are absent because they can only be made from a mix of multiple wavelengths. Colors containing only one wavelength are also called pure colors or spectral colors ...
The first human-made coherent light source was a maser.The acronym MASER stands for "Microwave Amplification by Stimulated Emission of Radiation". More precisely, it was the ammonia maser operating at 12.5 mm wavelength that was demonstrated by Gordon, Zeiger, and Townes in 1954. [1]
Infrared light with a wavelength longer than about 1400 nm is absorbed by the transparent parts of the eye before it reaches the retina, which means that the MPE for these wavelengths is higher than for visible light. In addition to the wavelength and exposure time, the MPE takes into account the spatial distribution of the light (from a laser ...
