Question

How does Gain-switching produce intensity spikes?

Answer 1

Gain switching is described in my lecture notes as "we simply control how long we supply energy to the laser for, and thus how long the laser remains above threshold for. As the laser only emits when the gain > loss, so a pulse of light may be formed." How does this create a pulse? To me this sounds akin to holding my hand over a flashlight and then quickly removing and putting my hand back to cover it. This doesn't seem like when I remove my hand more light will come out, the same but for a different amount of time. Not more power or anything we think of with pulsed lasers.

₳nswer :

➨ We can take the example of refraction in glass slab that refracts of the away.

➥ The light that comes and enters in the glass slab is refracted in the slab.

➭ Points to be remembered in refraction

➠Refraction is a apprison in our eyes that seems to be happen but not really.

➠Refraction takes place in many types substances.

➠I have explained the the method of refraction in glass slab.

➠I refraction the checking should be properly done.
