摘要： A laser treatment device provided with a laser light source, a laser-light transmitting optical fiber for transmitting laser light output from the laser light source and a probe for guiding the laser light transmitted by the laser-light transmitting optical fiber to an object to be irradiated. Further, the probe is constituted by a laser-light guiding optical fiber separated from the laser-light transmitting optical fiber. Moreover, a cooling chamber for cooling the optical fibers is provided in the neighborhood of an output end of the laser-light transmitting optical fiber, from which the transmitted laser light is output, and an input end of the laser-light guiding optical fiber, from which the laser light output by the laser-light transmitting optical fiber is input to the laser-light guiding optical fiber. Thereby, a medical treatment of a deep part of an affected or diseased region can be achieved without worsening the state of the exit of the laser-light transmitting optical-fiber. Moreover, the output end of the laser-light transmitting optical-fiber can be kept in a favorable condition even after the medical treatment of the deep part of the affected region. Thus there is no obstacle to the next treatment thereof.

摘要： In a laser surgical unit having a contact laser probe (1), a hydroxyl group (13) is included in the contact laser probe so that a laser beam is partially absorbed by the hydroxyl group (13) to heat the contact laser probe (1) for transmission to living tissue. Consequently, a coagulation layer is formed in the living tissue along with vaporization and incision. At least a part of the contact laser probe (1) is made of a material which contains the hydroxyl group (13) generally in an amount of between 0.5 and 10 ppm. Alternatively, the hydroxyl group (13) may be included only in a portion adjacent to a surface of a tip portion of the probe (1). As a further alternative, a coating film containing the hydroxyl group (13) may be attached to the tip of the contact laser probe (1). The laser beam preferably has a wavelength between 1.5 and 15 .mu.m. For example, use is made of an Er:YAG laser beam, a Ho:YAG laser beam, or a CO.sub.2 laser beam. The laser surgical unit of the above-mentioned structure is excellent in manipulatability, capable of safely and uniformly cutting living tissue, and capable of successively performing hemostasis.

摘要： A method of increasing the thermal shock resistance of a phosphate laser glass is described, comprising coating the surface of the glass with a sol solution which is prepared by hydrolyzing at least one organometallic compound dissolved in an organic solvent and then partially polycondensing, and then heat-treating to form a glassy coating on the surface of the glass. The phosphate laser glass having such increased thermal shock resistance is useful for high repetitive operation.

摘要： An antireflective coating and a process for producing the same are described. This antireflective coating has the difference in refractive index between the glass interface and the outer surface of the antireflected coating of 0.15 or less. This antireflective coating can be formed by treating a glass with an aqueous solution containing specified amounts of an acidic salt, Al.sup.3+ and Si.sup.4+. The antireflective coating has a high mechanical strength and optical elements having such an antireflective coating are useful for use in the laser nuclear fusion system.
