“…These methods are based on Z-scan approach [5], interferometric pump-probe configuration [15], integrated digital holography for measuring thermal lens (TL) and thermal mirror (TM) effects induced by femtosecond laser pulses [16], time-resolved digital holographic microscopy [17,18] etc. Meanwhile, the investigation of the spatial distribution of the samples with inhomogeneous nonlinear refractive index has been reported using point-by-point scanning of the sample [19,20].…”

“…In contrast with other methods for the investigation of nonlinear optical phenomena (e.g. [19,[22][23][24]), TRIDH approach can be implemented on a lensless optical setup where the pump beam is collimated [25], and no requirement of extremely high power density of a focused lased beam is needed. It provides higher stability of the optical setup and enables noninvasive investigation of the optical materials with low destruction threshold level.…”

“…Среди возможных техник измерения оптических нелинейных фоторефрактивных свойств можно выделить методы интерферометрии и цифровой голографии [4][5][6][7][8][9][10]. Ранее для решения задач измерения распределений нелинейного показателя преломления в образце было предложено использовать измерение локального нелинейного показателя преломления с поточечным сканированием образца [11,12]. Однако несмотря на успешность подобного подхода, он требует значительных временных затрат, особенно при сканировании больших образцов, и предполагает фокусировку лазерного излучения, приводящую к высоким плотностям мощности.…”

“…Fonte: Adaptada de GOMES. 102 Para o caso da figura 18, com a utilização de uma objetiva de 40x, os parâmetros do feixe de laser obtidos foram: ~4,5 μm; 0~1 μm; irradiação de pico 0~2 050 GW/cm 2 e potência média ~5,14 μW (com energia de ~5,14 nJ por pulso). Mas isso não significa que todas as medidas foram obtidas com esses mesmos parâmetros do gráfico da figura 18, os parâmetros podem ser ajustados todas as vezes em que forem realizados os experimentos, dependendo do que se vai medir, e principalmente de acordo com o material, é necessário, ajustar a intensidade do feixe de laser, com isso, a cada mudança é necessário recalibrar os parâmetros do feixe de laser, usando a mesma lamínula e os procedimentos descrito anteriormente.…”
