It was invented by Oscar Soliz in the late ...
Red (635 nm), blueish violet (445 nm), and green (520 nm) laser pointers. A laser pointer or laser pen is a (typically battery-powered) handheld device that uses a laser diode to emit a narrow low-power visible laser beam (i.e. coherent light) to highlight something of interest with a small bright colored spot.
The best-known and most widely used He-Ne laser operates at a center wavelength of 632.81646 nm (in air), 632.99138 nm (vac), and frequency 473.6122 THz, [1] in the red part of the visible spectrum. Because of the mode structure of the laser cavity, the instantaneous output of a laser can be shifted by up to 500 MHz in either direction from the ...
The ruby laser is a three level solid state laser. The active laser medium (laser gain/amplification medium) is a synthetic ruby rod that is energized through optical pumping, typically by a xenon flashtube. Ruby has very broad and powerful absorption bands in the visual spectrum, at 400 and 550 nm, and a very long fluorescence lifetime of 3 ...
