Argon-Ion+Lasers


 * Argon-Ion Lasers**

Argon-Ion Lasers Applet:  The argon-ion laser operates in the visible and ultraviolet spectral regions by utilizing an ionized species of the noble gas argon, which is the argon-ion laser's medium. Argon-ion lasers function in continuous wave mode when plasma electrons within the gaseous discharge collide with the excited laser species to produce light. This is a light wave.

This applet shows how argon-ion lasers work. By moving the laser wavelength, the laser's color changes. To understand more, need to know about the order of the visible light, which is ROY G BV, red, orange, yellow, green, blue, and violet. After violet, there is ultraviolet, which is invisible light. The wavelength slider, changing the laser wavelength, the color changes, and shows how the color of the output laser light changes. Using the tutorial speed slider, the speed changes, which can see the applet beam movement.

The way argon-ion lasers work is first, an energy comes out from the cathode assembly. The energy, or the light goes through bore segment, which is just like a canal. Then, the energy hit the output lens, and by reflection, the light goes back. Goes through, again, the bore segments, the energy hit the mirror at the other end of the laser. The light, back and forth couple times, have more energy to able to go through the light, the light, then, goes out the output lens.
