Abstract:
A mounting method for assembling a miser laser including a miser crystal in a miser stack, comprising:arranging the miser laser on a base surface of a housing, the housing including a side wall with a first housing window for allowing a miser beam to exit; directing from outside the housing a reference beam through the first housing window onto a first surface on a crystal end face of the miser crystal, the first surface being for light entry and light exit, the reference beam having approximately same wavelength, position, and spatial angular alignment as a miser beam to be generated later in the miser crystal, a direction of travel of the reference beam being opposite to a direction of travel of the miser beam to be generated later, the reference beam being aligned to travel parallel to the base surface of the housing and enclosing an angle of about 3.7 degrees with respect to a normal of the side wall having the first housing window; preadjusting the miser stack before mounting so that an angle between a normal of the crystal end face and the reference beam is approximately 45 degrees, the preadjusting being performed so that the reference beam strikes the crystal end face approximately at a center of the crystal end face, the preadjusting being performed using an adjusting device which permits a plurality of mutually independent movements, a first independent movement being in a direction parallel to the reference beam, a second independent movement being in a direction perpendicular to the reference beam and parallel to the housing base, and a third independent movement being a rotation about an axis of rotation perpendicular to the base surface of the housing; uniting on one of a display screen and a light-sensitive chip a plurality of reflected beams from the crystal end face by at least one of displacing the miser stack transverse to the direction of the reference beam and rotating, whereby a common reflection is formed; displacing the miser stack in the direction of the reference beam so that the plurality of reflected beams converge through a diaphragm stop and a condition of collinearity in a plane parallel to the base surface in the housing is fulfilled; and fixing the miser stack on the housing base.
