Abstract: A laser oscillator is provided with a folded laser resonator which includes an output coupling mirror (4), a rear mirror (10) and folding mirrors (11,12). The rear mirror (10) has a maximum reflectivity with respect to a linear polarization component of the laser beam, in which the linear polarization component has an E vector the direction of which is rotated from an incident plane of the nearest folding mirror by .pi./4. The folding mirrors (11,12) function as a whole as a phase retarder imposing a .pi./2 phase delay with respect to parallel and perpendicular polarization components of the laser beam, and accordingly, a circularly polarized laser beam is obtained from the laser oscillator.

Abstract: The invention describes a laser device (100) enabling controlled emission of individual laser beams (194). The laser device (100) comprises an optically pumped extended cavity laser with one gain element whereby a multitude of pump lasers (110) are provided in order to generate independent pump beams (191) and thus corresponding laser beams (194). The laser device (100) may be used to enable simplified or improved laser systems (500) as, for example, two or three-dimensional laser printers. The pump laser (110) may be VCSEL and the laser (160) may be a VECSEL monolithically integrated with the pump VCSEL array on the same substrate. Pump mirrors (140) and external cavity mirror (150) may be integrated into a single optical reflector with regions having different curvature. The laser emission is controlled by the pump light, i.e. transversal shape of the laser beam and/or number of laser beams is controlled by switching on/off the individual pump lasers (110).

Abstract: A vertical cavity surface emitting laser (VCSEL) includes a substrate having an aperture that allows light generated in an active layer of the VCSEL to exit the VCSEL after propagation through a first set of semiconductor layers. The VCSEL further includes an opaque bottom layer that blocks light generated in the active layer and propagated through a second set of semiconductor layers. The opaque bottom layer can be attached to a heat sink for heat dissipation thereby allowing the VCSEL to be operated at high power levels. The active layer is sandwiched between the first set of semiconductor layers and the second set of semiconductor layers. Unlike a traditional VCSEL where only certain wavelengths of light can propagate through a solid substrate that is “transparent” to these particular wavelengths, the aperture provided in the substrate of a VCSEL in accordance with the disclosure allows for propagation of many different wavelengths.

Abstract: The present disclosure discloses a CO2 laser and a method for the CO2 laser. The CO2 laser comprises an unstable laser cavity in the form of a first optical resonator having a semi-transparent output coupler (3), a laser medium (2) in the unstable laser cavity, and means (1) for exciting the laser medium (2). A part of the laser beam propagating beyond the light aperture of the output coupler (3) is directed to a second resonator, the second resonator comprising at least one focusing member (6), and the optical length of the second resonator being equal or multiple to the optical length of the first optical resonator. The part of the laser beam passing through the focal plane of the focusing member (6) is modulated by using a Q-switching device (8) in a manner that the excitation of the laser medium is in synchrony with the operation of the Q-switching device (8).

Abstract: A laser apparatus includes a laser medium; a light source that radiates light to the laser medium, thereby exciting the laser medium and raising the temperature thereof; a reflecting unit having a first plane that reflects light within a predetermined wavelength range from light generated by excitation of the laser medium; and an output mirror disposed opposite the reflecting unit, with the laser medium being interposed therebetween, and causing laser oscillation by inducing resonance of the light within a predetermined wavelength range between the first plane and the output mirror. The reflecting unit is configured to be movable between a position in which light resonance is induced between the output mirror and the first plane and the laser apparatus is set to an oscillation state and a position in which the laser apparatus is set to a non-oscillation state.
