We report on the laser cutting of carbon fiber reinforced plastics (CFRP) with a cw IR fiber laser (average power: 1kW). CFRP is a high strength composite material with a lightweight, and is increasingly being used various applications. A well-defined cutting of CFRP which were free of debris and thermal-damages around the grooves, were performed by the laser irradiation with a fast beam galvanometer scanning on a multiple-scan-pass method. © 2013 Copyright SPIE.

We report on the laser cutting of carbon fiber reinforced thermo-plastics (CFRTP) with a cw IR fiber laser (single-mode fiber laser, average power: 350 W). CFRTP is a high strength composite material with a lightweight, and is increasingly being used various applications. A well-defined cutting of CFRTP which were free of debris and thermal-damages around the grooves, were performed by the laser irradiation with a fast beam galvanometer scanning on a multiple-scanpass method. © 2014 SPIE.

We report on the laser cutting of carbon fiber reinforced thermo-plastic (CFRTP) and carbon fiber reinforced plastic (CFRP) with a cw IR fiber laser (average power: 2 kW). CFRTP and CFRP are a composite material which contains carbon fibers and binding plastics. A well-defined 2D laser cutting of CFRTP and CFRP flat plates which were free of debris around the groove was performed by the laser irradiation with a fast beam galvanometer scanning on a multiple-scan-pass method. The area of laser-induced damages in the samples was observed by microscopic X-ray Computed Tomography. Laser cutting with a high speed beam scanning exhibits a clean top and an excellent sidewall quality along with a negligible heat affected zone. In addition, the laser cutting of CFRP for a three-dimensional molded sample was performed with a five-axis laser cutting machine. © SPIE.

The dual beam of cw-350 W single-mode near-IR fiber laser and ns-pulsed-35 W UV laser were used in the experiments for cutting. The laser beam on the sample surface was scanned with a galvanometer scanner and focused with the f-theta lens of 400 mm focal length for IR and UV laser irradiations. A prototype remote scanner head for the multiple laser irradiations has been developed for a high-quality and high-speed laser processing of carbon fiber reinforced plastics (CFRP). In this paper, we report on the laser trepanning of circular patterns on CFRP. © 2014 SPIE.

Journal of Crystal Growth | Year: 2013

We have developed a laser-diode-heated floating zone (LDFZ) method, in order to improve the broad and inhomogeneous light focusing in the conventional lamp-heated floating zone method, which often causes difficulties in the crystal growth especially for the incongruently melting materials. We have simulated the light focusing properties of the LDFZ method to make the whole of the molten zone irradiated with concentrated and homogeneous laser lights. We have designed and assembled an LDFZ furnace, and have demonstrated how it works through actual crystal growth. The method is applicable to various kinds of materials, and enables stable and reproducible crystal growth even for the incongruently melting materials. We have succeeded in the crystal growth of representatives of the incongruently melting materials such as BiFeO3 and (La,Ba)2CuO4, which were believed to be difficult to be grown by the conventional method. Tolerance to the decentering of samples and highly efficient heating are also established in the LDFZ method. © 2012 Elsevier B.V. All rights reserved.

Miyachi Corporation | Date: 2012-04-10

An opto-isolator including a Faraday rotator comprised of a crystal cylinder formed into a cylinder using a crystal that rotates polarized light; an enclosing tube surrounding the crystal cylinder; two cooling tubes each sized and positioned to allow both ends of the outer peripheral surface of the crystal cylinder to be inscribed within the cooling tubes and both end sections of an inner peripheral surface of the enclosing tube to be circumscribed around the cooling tubes; passages formed within the cooling tubes; a cooling medium circulating through a space formed among the crystal cylinder, the enclosing tube, and the two cooling tubes, and the passages; and a magnet disposed in an outer periphery of the enclosing tube. The opto-isolator further includes two polarizers respectively disposed on the optical path of light entering the Faraday rotator and an optical path of the light exiting the Faraday rotator.
