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 ...
