Periodic surface structures have been observed on the end surfaces of synthetic silica fibres when they are exposed to long-term irradiation with light from a 405 nm CW diode laser. The surface structures are generated when the laser power is at a le

In the past, the degradation of 405 nm fiber-coupled diode laser systems was investigated in detail with focus on the input end. The coupling and transmission loss of the laser light was associated to the growth of a periodic structure on the input s

The current status of UV-damage in several different UV fibers due to defects in their synthetic high-OH silica core and cladding will be described. Further, steps to improve UV resistance and adequate measurement techniques based on a deuterium lamp

In the past, the spectral stability of multimode UV-fibers has been mainly characterized using deuterium lamps with a broadband spectrum in the DUV. In meantime, new UV light-sources with higher powers are available. For example, improved pulsed Nd:Y

Fiber-coupled 405 nm diode laser systems are rarely used with fiber output powers higher than 50 mW. A quick degradation of fiber-coupled high power modules with wavelengths in the lower range of the visible spectrum is known for several years. Meanw

For a delivery system using high OH polyimide coated all-silica multimode fibers the photo degradation and recovery were investigated for 355 nm pulsed laser radiation at a cryogenic temperature of 77 K (liquid nitrogen) and at room temperature, as r

Near-UV laser light is used for soft tissue treatment for several years now. In first applications the light was delivered directly from the laser, but for in vivo treatment more flexibility was needed. Multi-mode fibers can be used to achieve a high

High-order skew modes will be excited in multimode step-index fibers using special excitation conditions. As a result, light with an angle of incidence larger than the maximum angle for meridional modes given by the numerical aperture of the fiber ca

For applications of fiber guided pulsed UV-laser radiation in biomedical optics, laser spectroscopy or laser micro processing which need good beam quality low mode or single mode optical fibers are required. We investigated the transmission propertie
