Lasers for Holography

      Holography is divided into two processes which are recording and reproduction,the interference fringes is generated on the

holographic plate through the superposition between the reference light and the reflected light during the recording. Then, after the

holographic plate is processed in the darkroom, an image exactly same to the original object will be reproduced from the interference 

pattern on the photosensitive sheet by diffraction. Compared with ordinary photographic, Holography not only records the amplitude 

of light field of the object, but also records the relative phase of the reflected light waves. Holography is widely used in holographic

microscopy, holographic security, data storage, deformation measurement, holographic interferometry and etc.

     Changchun New Industries (CNI) founded in 1996, is a leading manufacturer of solid-state and diode laser systems. CNI laser features with high performance, nice reliability, and specifically designed for OEM, scientific, industrial and instrumentation use. In addition, CNI lasers are ISO-9001, FDA, CE, RoHS and JQA certified, CNI can provide the single longitudinal mode, long coherent length, high stability lasers for laser holography and relevant components also can be provided.
