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： The present invention relates to an atomic frequency acquisition device comprising a gas cell (400) filled with an atomic gas, a laser light source (100) emitting a laser beam which enters the gas cell (40) and excites a first energy transition of the atomic gas, a local oscillator (700) for generating an oscillator frequency in a frequency range including a frequency of a HFS transition of the atomic gas, and a modulator (600) modulating the laser light source (100) so as to emit laser radiation modulated with the oscillator frequency. An optical reflector (500) is arranged behind the gas cell (400) to reflect the laser beam after passage through the atomic gas so as to re-enter the laser cavity. A photodetector (200) detects beat frequencies caused by self-mixing interference within the laser cavity. A control unit (750, 800) controls the local oscillator (700) so as to periodically vary the oscillation frequency between two frequency margins which are adapted in such a way that a maximum beat frequency in the output signal of the photodetector (200) is within the two frequencies margins. The proposed device allows miniaturization and cost reduction by using a VCSEL with an integrated photodiode and achieves operation with fewer detection problems.

摘要： A sensor system is described, using self-mixing laser sensors (10) and an analyzer circuit (30) in order to determine the velocity of a vehicle, such as a car, and the rotational velocity of a wheel (20) of the car. Deviations between the velocity of the vehicle and the rotational velocity of the wheel (20) can be used to determine sliding of the wheel (20) and, finally, the traction or, more specifically, the coefficient of driving friction between the wheel (20) and the surface the car is driving on.

摘要： A discharge lamp, and particularly a high-pressure gas-discharge lamp (an HID (high-intensity discharge) lamp or UHP (ultra-high performance) lamp), having a reflector and a cooling means is described. The cooling means comprises at least one nozzle (3) by which a flow of gas can be directed onto the discharge lamp, the at least one nozzle (3) being so arranged that it does not extend, at least to any substantial degree, into a beam path produced by the lamp (2) and the reflector (1). In this way, the cooling means does not produce any obstacles on the beam path for the light. With preferred embodiments, it is possible to produce a turbulent flow that surrounds particularly the discharge vessel (21) of the lamp and that considerably increases the effectiveness of the cooling means. Further embodiments also allow the discharge lamp to be operated in a plurality of different positions without individual regions of the lamp being too little or too severely cooled.

摘要： An illumination unit is described having a light source (24), in particular a high-intensity discharge lamp or an ultra high performance lamp, a main reflector (1) and a back reflector (3) with an aperture opposite the main reflector, through which aperture light is reflected from the light source onto the main reflector. The illumination unit is in particular characterized in that the center of the light source (24) and the back reflector (3) are located or shaped relative to each other such that a first sector angle (L2-L2′) enclosed between the light source center and the edge of the back reflector (3) aperture is smaller than 180°. The efficiency of light emission can be considerably increased thereby. Preferred embodiments of the invention relate to various shapes of the back reflector (3) and the inner walls of the gas discharge space, as well as the shape of the part of the glass bulb that surrounds the gas discharge space, where each of these can cause a further increase in light output.
