Abstract:
1. A pulse compressor, comprising: a. a prism having a first end, an opposite, second end, and a body portion defined therebetween, wherein the body portion has at least a first surface and a second surface defining an angle, α, therebetween; b. a corner cube positioned to face the second surface of the body portion of the prism; and c. a periscope positioned to face the first surface of the body portion of the prism, wherein the prism, the corner cube and the periscope are arranged such that when an input beam of light along a first optical path is received and dispersed by the prism to form a first dispersed beam of light that is away from the second surface and along a second optical path towards the corner cube, the first dispersed beam of light along the second optical path is received and returned by the corner cube to form a first reversed beam of light that is along a third optical path towards the second surface, the first reversed beam of light along the third optical path is received and dispersed by the prism to form a second dispersed beam of light that is away from the first surface and along a fourth optical path towards the periscope, the second dispersed beam of light along the fourth optical path is received and directed by the periscope to form a returned beam of light along a fifth optical path towards the first surface, the returned beam of light along the fifth optical path is received and dispersed by the prism to form a third dispersed beam of light that is away from the second surface and along a sixth optical path towards the corner cube, the third dispersed beam of light along the sixth optical path is received and returned by the corner cube to form a second reversed beam of light that is along a seventh optical path towards the second surface, and the second reversed beam of light along the seventh optical path is received and dispersed by the prism to form an output beam of light along an eighth optical path.
