具有双光子光折变效应的光折变介质温度的变化对光伏孤子性质具有影响。通过光伏空间孤子的演化方程得到的亮和暗光伏空间孤子解与温度相关,在室温范围内,双光子光折变介质中空间孤子的光强和强度半峰全宽(FWHM)均受温度影响。随着介质温度的升高,双光子光折变介质支持光强较小的光伏空间孤子;在较大光强情况下,双光子光折变介质支持强度半峰全宽较小的光伏空间孤子;在小光强情况下,双光子光折变介质支持强度半峰全宽较大的光伏空间孤子。即可以通过控制光折变介质的温度来控制介质中光伏孤子的空间形态,从而在光折变介质中形成稳定的光伏空间孤子。
The temperature change of photorefractive media with two-photon photorefractive effect has an impact on the properties of photovoltaic solitons. The light and dark photovoltaic spatial soliton solutions obtained by the evolution equations of photovoltaic space solitons are temperature dependent. At room temperature, the FWHM of the spatial solitons in two-photon photorefractive media is affected by temperature . With the increase of medium temperature, the two-photon photorefractive media supports the smaller soliton space solitons, and the larger the intensity of light, the smaller the full width at half maximum of the photon photorefractive medium is In the case of small light intensity, the two-photon photorefractive media supports photovoltaic space solitons with large FWHM. That is, the temperature of the photorefractive media can be controlled to control the spatial shape of the photovoltaic solitons in the medium, so that a stable photovoltaic space soliton can be formed in the photorefractive media.
