The OKG technique, which exploits the optical Kerr effect (OKE), is one of the most used methods to determine the time response of transparent NL materials since its first demonstration [ 52 ], from which the origin of the nonlinearity can be inferred [ 42 ].
WebApr 1, 2024 · Exciton–polaritons in optical cavities exhibit strong nonlinearities predominantly because of the third-order Kerr-like interactions mediated by the excitonic component. Under quasi-resonant excitation, depending on the energy of the incident laser, it results in the optical limiting or bistable behavior. The latter phenomenon is manifested … WebMar 1, 2000 · According to researchers Kaoru Minoshima, Hirokazu Matsumoto, and Takeshi Yasui (now at Osaka University), the optical Kerr gate (an ultrafast optical switch that uses the optical Kerr effect) has several advantages as a tool for time-resolved imaging of diffusing surfaces. For example, real-time 2-D imaging and a wide spectral bandwidth are ...
