Abstract

A stark chirp pulse time broadening device is divided into two paths according to the light transmission direction, one is a first laser pump source, a first laser source, medium working cabin, a receiving device, the other is a second pump source, second laser source, a polarizer, an expander, a meidum working cabin connected with a vacuum pump by vacuum tubes and designed with an inlet and an outlet. The second laser source emits adjustable laser to enter into the expander for expansion after polarized by the polarizer to excite the working medium to split related energy level and light pulse emitted by the first source enters into the working medium cabin to generate dispersion and expanded on transmission time.

Description

Technical field: [0001] The present invention relates to a Stark chirped pulse time stretcher, in particular to an optical system for time stretching a Stark chirped pulse in a controllable manner. Background technique: [0002] In the prior art, A.M.Akulshin et al. "Light propagation in an atomic medium with steep and sign-reversible dispersion" (Light propagation in an atomic medium with steep and sign-reversible dispersion, Physical Review A 67 011801 (R) (2003) ) The paper discusses the mechanism and related experiments about the transparency and total absorption of pulsed light propagating in the atomic medium, but does not provide a practical instrument for time stretching of Stark chirped pulses. Invention content: [0003] The present invention solves the technical problem that there is no practical instrument for Stark chirp pulse time stretching in the prior art, and uses the light pulse to pass through the working medium whose energy level has been split, so tha...
