Abstract: An apparatus containing an optical emitter configured to emit optical radiation is provided. Further, the apparatus includes a first hermetically sealed measurement cell filled with a first gas. The first gas is configured to absorb the optical radiation at least partially at one or more predetermined wavelengths. Additionally, the apparatus includes a first microphone arranged in the measurement cell and configured to generate a first microphone signal on a basis of a photoacoustic excitation of the first gas by the optical radiation. The apparatus moreover includes an evaluation circuit configured to take the first microphone signal as a basis for generating a first measurement signal indicating an emission intensity of the optical emitter at the one or more predetermined wavelengths.

Abstract: A single shot autocorrelator for measuring duration of an ultrashort laser pulse in the far field, having a beam splitter to form two beams from an input ultrashort pulse: the reflected beam is firstly reflected by two mirrors mounted on a translation stage for adjusting time delay and subsequently a third mirror, and after focused by a spherical convex lens, enters a naturally grown strontium barium niobate crystal along the crystal z axis; the transmitted beam is firstly focused by a spherical convex lens, and after reflected by two mirrors, enters the crystal along the crystal z axis from opposite direction. The crystal is in the common focal regions of two spherical convex lenses and generates the transverse second harmonic pulse beam that is the autocorrelation signal to be recorded, which is imaged with an optical microscope onto a charge coupled device camera mounted perpendicular to the beams.

Abstract: There is described a photodetector for detecting incoming infrared light. The photodetector generally has a substrate; an i-type semiconductor region extending along the substrate, the i-type semiconductor region being sandwiched between a p-type semiconductor region and an n-type semiconductor region; a grating coupler being optically connected to one of two ends of the i-type semiconductor region, the grating coupler redirecting incoming infrared light into and along the i-type semiconductor region via the one of the two ends of the i-type semiconductor region for propagation of infrared light along the i-type semiconductor region; and a photocurrent detection circuit electrically connected to the p-type semiconductor region and to the n-type semiconductor region for detecting a photocurrent resulting from said propagation.

Abstract: A method of distinguishing effective pulses from test pulses in a scintillation detector that generates measurement light pulses includes providing a regularly-pulsed test light source that produces individual test light pulses having a time-dependent course of relative light intensity, which differs from a time-dependent course of relative light intensity of the measurement light pulses. The test light pulses are provided to a light detector for measurement of the test light pulses. The time-dependent courses of the relative light intensities of the test light pulses are analyzed. The measured pulses are separated into the test light pulses and the measurement light pulses according to the different time-dependent courses of the relative light intensities. The detector includes a scintillator, a light detector, a regularly-pulsed test light source that is adapted provide test light pulses to the light detector for measurement, and an electronic measuring circuit.
