Abstract
Systems and methods determining amplitude and phase versus frequency of an incoming beam of pulsed laser light. The incoming beam is split into two beams of substantially equal intensity, one of which is delayed for a delay period t. The two split beams are recombined to shine onto a thick SHG crystal at rotation angle θ and light emitted from the thick SHG crystal is detected as data and stored with reference to the delay period t and the angle θ. The thick SHG crystal is rotated by an angle δθ, and light is detected as data and stored until the thick SHG crystal has completed 360° of rotation. This is repeated for δt increases in the delay period until a selected beam delay period range has been completed. The stored data is processed to determine amplitude and phase versus frequency of the incoming beam of pulsed laser light.
