Abstract: A method for rewriting data in a three-dimensional optical memory element created in glass with ultrashort light pulse includes creating a bit due to a photo-induced contrast in index of refraction inside the glass in three dimensions depending of the strength of a first ultrashort-pulse laser beam. Then, irradiating the bit created in three dimensions with a second ultrashort-pulse laser beam having a lower energy than the strength of the first ultrashort-pulse laser beam while condensing the second ultrashort-pulse laser beam with an optical lens at a point shifted from the bit to be moved by a predetermined distance in an opposite direction from the direction of propagation of the first and second ultrashort pulse laser beams, thereby moving the bit for rewriting.

Abstract: A marking method is provided which permits an easy detecting of the presence of a mark without using a specific reading apparatus, and is capable of avoiding a damage as well as a strength deterioration of an object material. The marking method comprises: preparing a marking object; converging, into the marking object, a laser beam having a wave length range so chosen that the laser beam can transmit through a material forming the marking object, and then effecting a multiple photon absorption; and moving a converging position of the laser beam, in a manner such that an area, whose refractive index is changed due to the multiple photon absorption, can form a diffraction pattern capable of diffracting a visible light.

Abstract: The present invention proposes a method of and system for analyzing samples (particularly, bio-samples), wherein the continuous spectrum white light pulse generated from an ultra-short optical pulse is used in a simple manner. By a system according to the invention, continuous spectrum white light pulses generated by converging ultra-short optical pulses on a point in a transparent substance 23 are dispersed into a spectrum of light by a dispersing element 25, and a plurality of objective wavelength components are separately selected by small reflection mirrors 37, masked mirrors or the like. The selected objective wavelength components are combined by the dispersing element 25 into a composite optical pulse containing the objective wavelength components. The composite optical pulse is irradiated onto the bio-sample 28 or other samples, whereby only the desired fluorescent substances are excited by the objective wavelength components corresponding to them.
