Abstract: A mushroom-type hook strip for a hook-and-loop fastener has a flexible backing of thermoplastic resin and, is integral with backing, an array of upstanding stems distributed across at least one face of the backing, each having a mushroom head. The stems have a molecular orientation as evidenced by a birefringence value of at least 0.001. The mushroom-type hook strip can be produced continuously by injecting resin into cavities of a cylindrical mold while evacuating and cooling the cavities so that the cooled resin becomes molecularly oriented, thus affording to the stems excellent stiffness, durability, and tensile and flexural strength.

Abstract: A fiber optic telecommunication system with a pump laser and an optical amplifier is designed to stabilize the pump laser while preventing back reflections from the pump laser into the optical amplifier. The pump laser emits radiation at a shorter wavelength, while the optical amplifier emits radiation at a longer wavelength. An optical fiber is provided to connect the devices which has an ultraviolet photosensitive core, a low attenuation single mode wavelength region and a very high attenuation, longer wavelength region. The photosensitive core allows a weak Bragg grating to be written into the fiber, to stabilize the pump laser. Apparent fundamental mode cutoff is accomplished with a depressed well design to attenuate the unwanted back reflections from the pump laser into the amplifier. The pump laser is also protected from longer wavelength signal amplifier or signal laser radiation.
