| Title: | Low threshold ZnSe1-xTex optical limiters | Authors: | Ji, W. Tan, H.S. Feng, Z.C. Becla, P. |
Issue Date: | 1995 | Citation: | Ji, W.,Tan, H.S.,Feng, Z.C.,Becla, P. (1995). Low threshold ZnSe1-xTex optical limiters. Materials Research Society Symposium - Proceedings 374 : 79-84. ScholarBank@NUS Repository. | Abstract: | We report an experimental investigation of optical limiting with bulk ZnSe1-xTex crystals at wavelengths just below the band edge, using nanosecond laser pulses. The limiting threshold as low as a few mJ/cm2 has been demonstrated. The generation of free charge carriers by single-photon absorption, and subsequent free-carrier nonlinearities (nonlinear absorption and self-defocusing) are responsible for the limiting behavior. | Source Title: | Materials Research Society Symposium - Proceedings | URI: | http://scholarbank.nus.edu.sg/handle/10635/98783 | ISSN: | 02729172 |
