摘要： A surface emitting laser element includes a lower Bragg reflection mirror; an upper Bragg reflection mirror; and a resonator region formed between the lower Bragg reflection mirror and the upper Bragg reflection mirror, and including an active layer. A wavelength adjustment region is formed in the lower Bragg reflection mirror or the upper Bragg reflection mirror, and includes a second phase adjustment layer, a wavelength adjustment layer and a first phase adjustment layer, arranged in this order from a side where the resonator region is formed. An optical thickness of the wavelength adjustment region is approximately (2N+1)×λ/4, and the wavelength adjustment layer is formed at a position where an optical distance from an end of the wavelength adjustment region on the side of the resonator region is approximately M×λ/2, where λ is a wavelength of emitted light, M and N are positive integers, and M is N or less.

摘要： 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).

摘要： The present invention relates to a VCSEL array comprising several VCSELs arranged side by side on a common substrate (1). Each VCSEL is formed of at least a top mirror (5, 14), an active region (4), a current injection layer (3) and an undoped bottom semiconductor mirror (2). The current injection layer (3) is arranged between the active region (4) and the bottom semiconductor mirror (2). At least an upper layer of the substrate (1) is electrically conducting. Trenches (8) and/or holes are formed between the bottom semiconductor mirrors (2) of said VCSELs to said upper layer of said substrate (1). A metallization (9) electrically connects the upper layer of the substrate (1) with the current injection layer (3) through said trenches (8) and/or holes. The proposed VCSEL array allows a homogeneous current injection an has a high efficiency and power density.
