phase mismatch

The phase mismatch error is the main error source of sound intensity measurement system.

相位失配误差是声强测量系统的主要误差源,仅靠提高仪器的精度很难消除这一误差.

Based on phase mismatch compensation, a scheme of group velocity compensation in frequency tripling is designed by compensation principle of birefringence and polarization rotation.

在此基础上，设计了超短脉冲三倍频群速度补偿方案，方案采用了晶体双折射群速度补偿、以及极化旋转技术。

This paper discusses the dispersion compensation of wavelength phase mismatch in frequency-conversion of wide-band Nd+ 3: glass laser, including self-compensation of tandem crystals and compensation of dispersion components ( a prism or grating).

本文对宽频带钕玻璃激光频率转换中波长相位失配的色散补偿进行研究，包括晶体串接自补偿和色散元件棱镜与光栅的补偿。

The compensation for third-order nonlinearity effects is discussed. The results show that initial phase mismatch and inclusion of group-velocity mismatching can act to decrease the effects. The conversion efficiency can be increased with good temporal and spatial profiles of SH pulse with compensation methods. 5.

研究结果表明，初始相位失配与群速失配均能有效地补偿三阶非线性效应，提高转换效率，改善脉冲形状和光谱分布。
