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 laser diode chip removed and placed on the eye of a needle for scale A laser diode with the case cut away. The laser diode chip is the small black chip at the front; a photodiode at the back is used to control output power. SEM (scanning electron microscope) image of a commercial laser diode with its case and window cut away. The anode ...
A PIN diode switch can switch much more quickly (e.g., 1 microsecond), although at lower RF frequencies it isn't reasonable to expect switching times in the same order of magnitude as the RF period. For example, the capacitance of an "off"-state discrete PIN diode might be 1 pF. At 320 MHz, the capacitive reactance of 1 pF is 497 ohms:
Laser guidance is used by military to guide a missile or other projectile or vehicle to a target by means of a laser beam, either beam riding guidance or semi-active laser homing (SALH). [7] With this technique, a laser is kept pointed at the target and the laser radiation bounces off the target and is scattered in all directions (this is known ...

Around 1980, Michael W. Berns, a professor of biology at the University of California, Irvine, founded an institute focusing on the then-new technology of lasers.After receiving a National Institutes of Health biotechnology grant, [3]: 328–331 he established a laboratory for laser microscopy, the Laser Microbeam Program (LAMP).

In 1967, in response to industry demands, she founded and launched Optical Spectra. In 1982 the magazine's name was changed to Photonics Spectra to reflect the growing influence of these new light-based technologies. [1] Today, the worldwide distribution of Photonics Spectra is over 100,000 copies. [2]
A krypton fluoride laser (KrF laser) is a particular type of excimer laser, [1] which is sometimes (more correctly) called an exciplex laser. With its 248 nanometer wavelength, it is a deep ultraviolet laser which is commonly used in the production of semiconductor integrated circuits , industrial micromachining, and scientific research.
