    摘要： The present invention relates to a switchable dual wavelength solid state laser with a solid state gain medium (1) which is selected to emit optical radiation at a first wavelength with a first polarization and of at least a second wavelength with a second polarization different from said first polarization when optically or electrically pumped. A polarizing device (7) is arranged within the laser cavity, said polarizing device (7) being adjustable at least between said first and said second polarization. The two end mirrors (2, 3) of the laser cavity are designed to allow lasing of the solid state laser at the first wavelength when the polarizing device (7) is adjusted to the first polarization, and to allow lasing of the solid state laser at the second wavelength when the polarizing device (7) is adjusted to the second polarization. The proposed solid state laser allows an easy switching between two emission wavelengths.

    摘要： A system is described which enables parameters of a tire (20) to be measured by means of self-mixing laser interferometry. Laser sensors (1) using self-mixing laser interferometry can measure distances and/or speed of surface elements of a tire (20). Consequently, a system comprising such a laser sensor (1) can for example be used to measure and indicate tire tread wear, tire load or speed. In comparison with laser sensor based systems using the well-known time of flight method, the described system is simple, cost effective and, due to the small size of the laser sensor (1), can easily be integrated in cars.

    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 present invention relates to a method of switching laser emission of a solid state laser between different emission wavelengths, said different emission wavelengths being based on different electronic transitions in a solid state laser medium (3) of the solid state laser. The at least two end mirrors (1, 2) of the solid state laser are designed to allow lasing of the laser at the different emission wavelengths and coupling out of the different emission wavelengths at one end mirror (2) of the laser cavity. The switching of the laser emission is achieved by switching the cavity length of the laser cavity between different cavity lengths, wherein the different cavity lengths are selected such that at each of the cavity lengths the solid state laser lases at only one of the different emission wavelengths which is different from the emission wavelengths at the other of the selected cavity lengths. With the method and corresponding device an easy switching between emission wavelengths of a solid state laser is possible.

    摘要翻译： 本发明涉及一种在不同发射波长之间切换固体激光器的激光发射的方法，所述不同发射波长基于固态激光器的固态激光介质（3）中的不同电子跃迁。 固体激光器的至少两个端面镜（1,2）被设计成允许激光器以不同的发射波长发生激光并且在激光腔的一个端镜（2）处耦合出不同的发射波长。 激光发射的切换通过在不同的腔长度之间切换激光腔的空腔长度来实现，其中选择不同的腔长度，使得在每个腔长度处，固态激光仅在不同的发射波长中的一个处发射 其与所选择的腔长度中的另一个处的发射波长不同。 利用该方法和相应的装置，固态激光器的发射波长之间容易切换​​是可能的。
