Electrical pumping is another method of laser pumping; it involves passing an electric current through the gain medium to excite the atoms or molecules. This is the pumping mechanism used in virtually all gas lasers, where the flow of electricity through a low-pressure gas creates a plasma. 6, record 1, English, - electrical%20pumping

Pour provoquer l'émission laser, il faut exciter correctement un milieu actif afin de placer ses atomes, ses ions ou ses molécules dans des conditions telles qu'ils puissent libérer de l'énergie par émission stimulée. Cette excitation, appelée «pompage», peut se faire sous des formes différentes : - pompage électrique : décharge électrique dans un gaz avec excitation électronique, par exemple [...] 3, record 1, French, - pompage%20%C3%A9lectrique

In order to use... a [laser] medium as [an] optical oscillator, the optical gain arising from the inverted population must exceed the loss in the resonator... To accomplish this, the optical path through the laser material is made long in one direction, and highly reflecting mirrors are placed so that they send the light back and forth along the length of the material. The mirrors provide feedback... and thereby convert the optical amplifier into an optical oscillator. Oscillation than takes place only between the mirrors. 3, record 4, English, - oscillator
