    Abstract: The invention relates to a high-pressure discharge lamp with a discharge vessel having a filling comprising a rare gas, for example argon, mercury, and chlorine, wherein the filling quantities of mercury [Hg] and chlorine [Cl] comply with the following conditions: [Hg].[Cl]>=200 (mumole/cm 3 ) 2 , [Cl] 3 . The condition [Hg].[Cl]>=200 (mumole/cm 3 ) 2 achieves HgCl vapor pressures in the discharge sufficient for generating significant radiation components of the B 2 Sigma + -X 2 Sigma + band system of this molecule. The condition [Cl] 3 serves to limit the chemical aggressiveness of the chlorine filling, in particular to limit the attacks on the wall and electrodes and thus to achieve longer lamp lives. The addition of chlorine-binding metals, in particular of germanium, leads to a further improvement in the radiation and life properties of the lamp.

    Abstract: The present invention relates to a method and device for detecting coherent optical radiation. In the proposed method, an emission wavelength (8) of a laser (5) is tuned or set close to a wavelength (9) of the coherent radiation (3) to be detected. The coherent radiation (3) is coupled into the laser cavity and a resulting periodic modulation in output power of the laser emission of the laser are measured or detected. The proposed method and device are only sensitive to coherent radiation in a narrow wavelength range.

    Abstract: Methods of driving a gas discharge lamp (1). In a first method, a value of voltage (Ul) across the gas discharge lamp (1) is determined, then a correction function (Kd) representing the dependency of light flux on a discharge arc length (d) is applied to calculate a required lamp power value (Pr) for a target light flux value (Ul). Finally, the gas discharge lamp (1) is operated according to the required lamp power value (Pr). In a second method, a value of voltage (Ul) across the gas discharge lamp (1) and a value of pressure (pl) inside the gas discharge lamp (1) are determined, then a correction function (Kp) representing the dependency of light flux on a discharge arc length (d) is applied to calculate a required lamp pressure value (pr) for a target light flux value by using the lamp voltage value (Ul) and the lamp pressure value (pl). Finally, the gas discharge lamp (1) is operated according to the required lamp pressure value (pr). Furthermore, the invention relates to appropriate driving units (4, 58) for driving a gas discharge lamp (1) and to an image rendering system, particulary a projector system, comprising gas discharge lamps (1) and such driving units (4, 58).
