    摘要: It is an object of the invention to provide a simple setup of a waveguide laser which allows to control the emission of specific laser wavelengths in a laser material having laser transitions of similar wavelengths. For this purpose a core (4) forming a gain medium is provided with a cladding (6) which introduces losses to an undesired laser transition but is transparent to the light of a desired laser transition. A second cladding (8) is provided for guiding the laser radiation. Pr: ZBLAN with a Tb: doped cladding may be used. Instead of the absorbing cladding (6) a photonic crystal (20) may be used. The laser is end-pumped by a laser diode (14).

    摘要: The invention relates to a lighting apparatus for generating light. A primary light generator generates primary light (6), which is converted by a light converting material (8) into secondary light (3), wherein the primary light is directed to a primary surface (9) of the light converting material. An enclosure (10) comprising a transparent cover (7) hermetically encloses the light converting material, wherein the transparent cover is transparent to the primary light and located on the primary surface of the light converting material. The enclosure increases the photostability of the light converting material. This allows increasing the intensity of the primary light by, for example, increasing the power of the primary light and, thus,of the secondary light, and/or by focusing the primary light onto a smaller area on the primary surface, thereby allowing decreasing the optical Étendue of the secondary light, without damaging the light converting material.

In this method an operating frequency of the lamp is switched from a first frequency value (fi) to a second frequency value (f2), which second frequency • (f 2) value is higher than the first frequency value (fi)′, if a first time criterion pertaining to a duration of driving of the lamp (1) in the second operation mode (OMn) is fulfilled and the operating frequency is switched from the second frequency value (f2) to the first frequency value (fi), if a second time criterion pertaining to a duration of driving of the lamp (1) in the first operation mode (OMP) is fulfilled.
