Embodiment Construction
[0035] Below we will introduce the implementation of the method in detail in conjunction with the accompanying drawings.
[0036] Such as figure 1 As shown, the supercontinuum pulsed laser measurement device based on nonlinear nanomaterials includes a 1 / 2 wave plate 1, a polarization splitting device 2, an electric stepping motor 3, a first high reflection mirror 4, a second high reflection mirror 5, The third highly reflective lens 6, laser line filter 7, focusing lens 8, photonic crystal fiber 9, collimator lens 10, optical filter 11, fourth highly reflective lens 12, fifth highly reflective lens 13, achromatic focusing Lens 14, nonlinear nano material 15, collecting and focusing lens 16, spectrometer 17, PC 18.
[0037] The 1 / 2 wave plate 1 is set directly in front of the polarization beam splitting device 2 to change the polarization splitting ratio; the ultrashort pulse laser passes through the 1 / 2 wave plate and then enters the polarization beam splitting device 2 for lig...
