An optical pulse measuring method measuring an optical pulse generated from a pulse light source is provided. The method includes: splitting the optical pulse and then focusing them at a measuring point, so as to generate gas plasma by the autocorrelation of the split optical pulses; receiving the sound signal from the gas plasma and generate a plasma sound signal; and using the plasma sound signal to calculate the characteristics of the optical pulse. A measuring device is also provided.

Measuring device and measuring method

A simple method is developed in the present invention for fabricating periodic ripple microstructures on the surface of an ITO film by using single-beam femtosecond laser pulses. The periodic ripple microstructures composed of self-organized nanodots can be directly fabricated through the irradiation of the femtosecond laser, without scanning. The ripple spacing of &#x2dc;800 nm, &#x2dc;400 nm and &#x2dc;200 nm observed in the periodic ripple microstructures can be attributed to the interference between the incident light and the scattering light of the femtosecond laser from the surface of the ITO film. In the present invention, the self-organized dots are formed by the constructive interference formed in the surface of the ITO film, where includes higher energy to break the In&#x2014;O and Sn&#x2014;O bonds and then form the In&#x2014;In bonds. Therefore, the dots have higher surface current greater than other disconstructive regions of the ITO film.

A method of joining superconductor materials is described. A microwave chamber including a first heat absorption plate and a second heat absorption plate corresponding to the first absorption plate is provided. A first superconductor material and a second superconductor material are disposed between the first heat absorption plate and the second heat absorption plate in the microwave chamber. The first superconductor material and the second superconductor material have an overlapping region therebetween, and a pressure is applied to the first heat absorption plate and the second heat absorption plate. Microwave power is supplied to the microwave chamber. The first heat absorption plate and the second heat absorption plate transform the microwave power into thermal energy so as to join the first superconductor material and the second superconductor material at the overlapping region.
