TEM, beam output through the film Points) 3 Posts ator is to be amplified in another laser-culty pulse is injected in an arbitrary way, the Comican 0 mode in the second cavity. In that case it will be ear combination of different normal modes of the sound ative cavity is 1.25m long, with one flat mirror and one mister 5 m. The laser pulse is injected through the flat mirror (an over- 1, actually). The distance between the oscillator and regenerative is 4 lens or lenses are required to take the output of the cavity and introduce the second cavity as a matched mode? Specify values and locations Points) e. A laser physics student tries this but finds he has a small error and finds that in the regenerative he has both TEM, and some TEM, modes operating. A portion of the light output from the regenerative is collected onto a photoőiode and he records the signal on a fast oscilloscope. Describe the signal that the student will observe on his oscilloscope. If he cannot get the mode-matching perfect, what else can he do to minimize this problem?
