    摘要: The present invention relates to a process for producing high-quality crystals of protein or organic substances easily and efficiently. A solution of protein or an organic substance is prepared and then is cooled slowly to be supersaturated to a low degree. This supersaturated solution is irradiated with a femtosecond laser 10. A local explosion phenomenon occurs at the focal point of the laser and thereby a crystalline nucleus is generated. A high-quality crystal is obtained when a crystal is grown on the crystalline nucleus over a long period of time. The femtosecond laser to be used herein can be a titanium:sapphire laser having a wavelength of 800 nm, a duration of 120 fs, a frequency of 1 kHz, and an output of 400 mW.

    摘要: A method for analyzing a sample in a liquid is provided, which is suitable for easily and reliably preventing a liquid for analysis from being evaporated. When the sample in the liquid is observed by using a scanning probe microscope (SPM), a sealing liquid (17) immiscible with a liquid for analysis (16) is filled around the liquid for analysis (16), in which a sample (13) and a probe (15) are immersed, so as to form a sealing state, in which the liquid for analysis (16) is isolated from an external gas. The SPM enables the probe (15) disposed on a front end of a cantilever (14) to approach a surface of the sample (13) immersed in the liquid, scans the surface of the sample, and detects an interaction between the sample (13) and the probe (15), thereby generating an image.

    摘要: A method of processing a surface of a nitride semiconductor crystal, wherein a surface of a nitride semiconductor crystal is brought into contact with a liquid containing at least Na, Li or Ca as a processing solution. In the method, the processing solution can be a liquid containing at least Na, having an Na content of 5-95 mol %. The processing solution can be a liquid containing at least Li, having an Li content of 5-100 mol %. A nitride semiconductor crystal having a maximum depth of a surface scratch of at most 0.01 μm or an average thickness of a damaged layer of at most 2 μm. Consequently, a method of processing a surface of a nitride semiconductor crystal with a decreased depth of a surface scratch or a decreased thickness of a damaged layer, and a nitride semiconductor crystal obtained with the method can be provided.

    摘要: An optical wavelength conversion element includes a cesium-lithium-borate crystal processed into a 10-mm long optical element cut in an orientation that allows a fourth harmonic of a Nd:YAG laser to be generated. A transmittance (Ta) at 3589 cm−1 in an infrared transmission spectrum of the optical element is used as an index that indicates a content of water impurities in the crystal and is independent of a polarization direction. An actual measurement of the transmittance Ta is at least 1%, without taking into account loss at an optically polished surface of the crystal. A wavelength conversion device, a ultraviolet laser irradiation apparatus, a laser processing system, and a method of manufacturing an optical wavelength conversion element are also described.
