Light Shift (22 March 2004 – 2014) was an American-bred, British-bred Thoroughbred racehorse and broodmare best known for winning the 2007 Epsom Oaks. In a racing career which lasted from June 2006 to October 2007 the filly ran nine times and won four races. After winning once as a two-year-old, Light Shift won the Cheshire Oaks on her second appearance as a three-year-old. She then won the Classic Oaks over one and a half miles at Epsom, beating the Irish filly Peeping Fawn. Light Shift never won another race, being beaten by Peeping Fawn in the Irish Oaks and the Nassau Stakes and finishing unplaced in the Prix de l'Opera.

InactiveCN102231476AReduce output powerIncreased Raman Gain BandwidthExcitation process/apparatusSemiconductor laser excitation apparatusRayleigh scatteringRefractive index
The invention provides a random fiber laser system and belongs to the novel laser device field. In the system, a traditional single-mode fiber is taken as a laser medium, and a cascaded semiconductor laser is taken as pump light which is coupled to the fiber along an opposite direction from a middle point of the fiber. Photon is in propagation in the fiber, scattering is generated because of nonuniform random refractive index, and distributed Rayleigh scattering is formed. The pump light provides distributed Raman gain along the fiber. When total gain is greater than total loss, backward scattered photon is amplified to generate laser. Frequency of random laser is a result of frequency of last grade pump light shifting downward with 13 THz. By properly selecting pump light, output of the random laser in a whole fiber transparent window is realized. By using cascaded semiconductor laser as the pump light, not only is Raman gain spectrum bandwidth increased, but also Raman gain form is controlled. Thereby the random laser in the invention has the characteristics of controllable mode, super-long transmission, low threshold, high output power and the like.

A light shift compensation device of an image composition device for the multicolor holography utilizes a light source provider to emit a beam split into an object beam and a reference beam via a beamsplitting unit. The object beam, shined on a projecting unit, is transformed into an object wave for projecting two-D images of the object on a negative. The reference beam is transformed into a reference wave by a compensating unit to adjust the irradiation angle and thence project on the negative. Interference fringes formed by the object wave and the reference wave projecting on the negative record two-D images of the object on the negative. The two-D images projected by the object wave are separated into the red image, the green image, and the blue image, which are directed to the three fundamental colors. The image of one single color is adopted for being recorded on the negative each time. The images of the three fundamental colors are successively processed by three times of double-exposure on the negative to compose a true color image. The angle of projection of the reference wave is adjusted by the compensating unit, so that the angles of diffraction of the green image and the blue image recorded on the negative are changed.
