Nonlinear Optical Studies on Iodine Solutions

Abstract

Optical phase conjugation via degenerate four-wave mixing is studied in iodine solutions under pulsed laser radiation at two wavelengths (532 nm and 694 nm). The effect of using four different solvents (1,2-dibromoethane, xylene, methanol and ethanol) is studied at 532 nm. Phase conjugate reflectivities in the range of 01% to 03% are observed. The solutions exhibit a maximum reflectivity at an optimum concentration. The experimental data is analysed using the Caro-Gower model.

The phase conjugation of degenerate four-wave mixing (DFWM) was observed by irradiating an excimer laser pumped dye laser to iodine/benzene solution. It is confirmed that the generated light intensity shows guadratic proportion to the absorbance of solution.

Amplified phase conjugate reflection of KrF laser radiation

R. G., M. C. Gower

We report amplified phase conjugate reflection of KrF laser radiation at 249 nm using degenerate four-wave mixing in a solution of rhodamine 6G in ethanol. Reflectivities of ∼300% have been measured. Saturation of the reflectivity at high probe intensities was observed and the temporal dependence of the reflectivity has been investigated. The importance of mutual coherence of the probe and pump for the thermally induced nonlinearity involved in the process has been demonstrated.

Ultraviolet Phase Conjugation And Its Practical Implications

B. J. Feldman, Robert A. Fisher, S. L. Shapiro

We report the first demonstration of uv phase conjugation. Using a 15 psec, 2660 Å pulse, 0.1% conjugate reflectivities were obtained via degenerate four-wave mixing in 1-mm samples of CS2 mixtures. While pure CS2 did not exhibit the effect, dilution in several uv transmitting solvents opened up a concentration-tunable (2450 Å - 2850 Å) spectral window, allowing the optical Kerr effect to be utilized. Weaker phase conjugation at 2660 Å was also observed in other Kerr media and in saturable absorber media.

Optical phase conjugation by resonant degenerate four-wave mixing in liquid phase medium

Fan Rong-Wei, Deying Chen, Fang Tao +3 more

In this paper, frequency-doubled Nd:YAG laser's phase conjugation has been investigated experimentally using resonant degenerate four-wave mixing (DFWM). The iodine solution was used as resonant medium. In this way, the energy of the DFWM phase conjugation beam arrived at 43μJ/pulse while the total pump beam's energy reached 8mJ/pulse. The relation between the pulse energy of the DFWM phase conjugation beam and that of the pump beam was investigated. We also measured the optical field distributions of pump beam and DFWM phase conjugation beam, from which it can be noticed that the DFWM phase conjugation can improve the laser beam quality. At the same time, we observed the influence of the pump beam's disturbance on the DFWM signal.

Phase Conjugation by Degenerate Four-wave Mixing in Inverted Dye Solutions

P.A. Routledge, Terence A. King

Phase conjugation has been observed in an amplifying medium of rhodamine 6G dye molecules in solution, excited either by flashlamps or by a laser. It is found that the mechanism involved in phase conjugation is degenerate four-wave mixing through gain saturation, and reasonable agreement obtained with the theory of saturable amplifiers. A phase-conjugate signal was observed over the tuning range of the dye system (580–605 nm) and a reflectivity up to a maximum of 25% was obtained.
