摘要： Method to arrange and adjust a laser that is stable with respect to external and internal influences, and which comprises at least three optical components consisting of a laser element (1), which can generate optical radiation within a wavelength band lambda 1 - lambda 2, an optical collimator (2) that inside the laser collimates radiation emitted from the laser element, and a plane reflection grating (3) with parallel grating grooves, arranged such that the latter together with a flat reflection surface, which can be one end surface of the laser element, forms a resonator, that selects the radiation wavelength emitted by the laser. At least one optical component, which for instance can be (1), (2) or (3) is fixedly mounted in a holder, that for the purpose of adjusting the laser to a lasing condition can be turned about an axis, that is fixed in the device, such that the angle PHI between two directions, which are defined by the direction along the grating grooves (G) and by the direction of collimation (LO) of the radiation, varies within an interval that contains PHI = 90 DEG and such that collimated radiation from the laser element, which at PHI = 90 DEG is reflected back from the grating and returns to the radiation emitting portion of the laser element via the collimator (2), has a selected wavelength that lies within the band lambda 1 - lambda 2.

摘要： The present invention relates to a device for lash free positioning of especially components used in optical and optoelectronical equipments relatively to a fixed reference unit (29) using at least two interconnected elastic blocks (11, 12) each consisting of two base elements placed at a distance from each other and interconnected by elastic elements (17, 19), constituting a cantilevered system as related to one of the base elements. To the system a holder (22) is attached, on which the components to be positioned are fixed, that each elastic block (11, 12) is essentially rigid along a main axis (z) of the elastically undeformed cantilevered system, and is elastic in directions perpendicular to the axis, that the device has mechanisms for adjustment which apply adjustable forces between the basic element (13), or between some other to the latter fixedly joined element, and the cantilevered system or an arm fixed to this system, which latter may be the holder (22), acting in chosen directions, which translate or turn the component holder (22), when the elastic elements (17, 19) are elastically deformed.

摘要： Method and apparatus to ensure tuning without mode hopping of the resonator frequency and tuning of the Q-value of an optical resonator of the type comprising a partially reflecting resonator mirror (2) and a movable reflecting optical grating, with grooves (GR) parallel to the resonator mirror, intended to function as a wavelength selective reflector and which may comprise optical elements between the mirror and the grating, said optical elements being intended for collimation, amplification (4) and filtering of the radiation in the resonator, so that when changing the resonance wavelength ( lambda ) of the resonator or its Q-value, the grating is moved in such a way that a line (C) on the grating which is defined at a tuned initial position of the resonator by the intersection of the plane of grating grooves (M) and the virtual mirror plane (5) of the resonator mirror, remains at a distance less than lambda /4 from the virtual mirror plane, which as a result of chromatic dispersion in the resonator media slides in distance to the fixed mirror with said resonator wavelength during the movement.
