Abstract

Provided is a horizontal guide rail pumping bidirectional stimulated scattering simultaneous generation and enhancement device, characterized by comprising a signal light source (1), a dichroscope (2), a first half-transparent and half-reflecting mirror (4) backscattering signal light, a first half-transparent and half-reflecting mirror (5) forescattering signal light, an oval scattering medium container (10), a second half-transparent and half-reflecting mirror (5) forescattering signal light, a second half-transparent and half-reflecting mirror (4) backscattering signal light, and a forward scattering signal light detector (11) arranged in sequence along a light path. The reflection direction of the dichroscope (2) is provided with a back scattering signal light detector (3). The device also comprises a horizontal guide rail (7) arranged on the position close to the oval scattering medium container. The horizontal guide rail (7) is provided with a pumping light source (6) which can horizontally move along the horizontal guide rail. The pitch angles of the pumping light source (6) can be adjusted at will.

[0002] Stimulated scattering in the prior art generally includes two types of forward scattering and backward scattering, in which different optical designs are designed for each type of scattering in order to enhance the reception and analysis of stimulated scattering signals. However, many times we need Simultaneously carry out scattering measurements in the front and rear directions to effectively analyze the experimental data. At this time, in order to complete such work, it is necessary to conduct two experiments separately and design two different optical paths, resulting in a very large increase in time cost, and , for the separate forward scattering and backscattering, the defects of both are mainly concentrated on two points. The first point is that when the pump light intensity is not particularly large, the stimulated scattered signal light generated is abnormally small. When using a high-sensitivity instrument to analyze the stimulated signal light, such as ICCD, this instrument is expensive and requires a high operating environment. If you want to use a low-cost signal analysis instrument, you need to use a high-power Lasers, but high-power lasers cost more; the second point is that the intersection angle of pump light and signal light cannot be adjusted. There are adjustable ones in the prior art, but there is no one that can adjust bidirectional scattering, especially for There are basically no two-way adjustable angles in the forward and backward directions, which greatly limits the flexibility of the experiment
