Abstract: A laser diode structure for generating a collimated or divergent laser beam, preferably for application in gas detection, with a laser diode arranged in a closed housing, with the housing comprising a housing bottom, an exit window, electrical connections, a temperature control device for the laser diode, and an optical element for influencing the laser beam. The temperature control device carrying the laser diode is arranged on the housing bottom and the optical element is positioned at a distance from the laser diode. The invention proposes an electrically controllable power device for the cyclic alteration of the position and/or alignment of the optical element in relation to the laser diode so that the optical path length for the laser beam in the housing changes periodically. The oscillating motion of the optical element has the effect of time-averaging the etalon and/or self-mixing effects caused by the back-reflections of the laser beam in the housing, thereby reducing the optical noise of the laser diode structure.

Abstract: The invention relates to a laser diode structure, specifically for use in gas detection, with a hermetically sealed housing with electrical connections having a bottom and a window. A laser diode chip and a temperature control system for the laser diode chip are provided in the housing. A thermo element in the form of a Peltier element forms the temperature control system, and is connected via a lower flat surface to the bottom of the housing and via an upper flat surface to the laser diode chip, with a temperature-controlled beam shaping element as collimator provided between the laser diode chip and the window of the housing that acts on a laser beam emerging from a laser aperture of the laser diode chip before it passes through the window. The beam shaping element is in contact with the laser diode chip and is preferably connected via a boundary surface to the laser aperture with surface-to-surface contact or adhesively, or is made in one piece together with the laser aperture.
