    摘要： An optical isolator with a collimator which is used at the tip end of a laser beam transmitting fiber utilized in a laser processing. The optical isolator can provide solutions to the problems how to make return lights to be isolated from an incident light path and how to prevent the light energy from being conducted to an incident fiber, a laser oscillator, the collimator, and the optical isolator. The solutions comprise light-receiving fibers (22 and 23) disposed at focal points of a collimator lens (5) to which reflected lights from a workpiece return through the optical isolator. The return lights are then led to a ceramic tube (24) where the return light energy is converted to thermal energy and dissipated.

    摘要： An optical transmitter includes an optical isolator that includes a Faraday rotator transmitting light output from a light source, and has a first state in which the light is transmitted through the optical isolator when a first magnetic field is applied to the Faraday rotator, and a second state in which the amount of the light transmitted through the optical isolator is less than that in the first state when a second magnetic field different from the first magnetic field is applied to the Faraday rotator; a junction to which an optical transmission medium into which the light output from the optical isolator is input is connected; a magnetic-field generator that selectively applies the first magnetic field or the second magnetic field to the Faraday rotator; and a switching unit that switches the magnetic-field generator to the second state when the optical transmission medium is not connected to the junction.

    摘要： An optical device (10) is described that may be used to split a beam of light into two or more components of light or combine two or more components of light into a combined beam of light. The optical device may also provide isolation (i.e., inhibit optical feedback) in the reverse direction. The beam of light (39) may be split into two or more polarized components of light (56, 58). Similarly, the two or more components of light that are combined may be polarized. The optical device may be coupled to optical fibers for both input and output of the beam of light or the two or more components of light.
