Fibre-type wavelength converison device |
摘要 |
A fibre-type light conversion device for converting the wavelength of an incident light comprises a core and a cladding layer provided around the core. An end surface of the device from which the light beam radiates is made conical, so that the second harmonic wave is collimated without using any additional optical element such as a conical prism. The end surface of the device is formed by a process in which the end surface of the device is polished with a central axis of the device being held at a predetermined angle with respect to a polishing surface while the device is rotated about the central axis.
