摘要： A beam generating device includes a semiconductor substrate, having an optical passband. A first array of vertical-cavity surface-emitting lasers (VCSELs) is formed on a first face of the semiconductor substrate and are configured to emit respective laser beams through the substrate at a wavelength within the passband. A second array of microlenses is formed on a second face of the semiconductor substrate in respective alignment with the VCSELs so as to transmit the laser beams generated by the VCSELs. The VCSELs are configured to be driven to emit the laser beams in predefined groups in order to change a characteristic of the laser beams.

摘要： Disclosed are a light source system and a laser light source (300). The laser light source includes two groups of laser groups (20a, 20b), wherein at least one group of laser groups includes at least two lasers (21a, 21b, 21c, 21d), and the light beams (L1) generated by the two groups of laser groups are in the same direction and parallel to each other. The first projections of the two groups of laser groups on the cross section of the light beams formed by the respective emergent light rays thereof are partially overlapped with the second projections in a first direction, which first direction is the connection direction of at least two laser centres of a group of laser groups. The laser light source has the effects of being able to effectively increase the light power density and at the same time reduce the volume of the light source.

摘要： An optical device may include a semiconductor laser chip to independently generate four laser beams at different wavelengths. Each laser beam, of the four laser beams, may be directed to a respective optical output of the optical device with a sub-micron level of tolerance of each laser beam relative to the respective optical outputs of the optical device, and each laser beam, of the four laser beams, may be associated with a different optical path from the semiconductor laser chip to the respective optical output of the optical device. The optical device may include a lens to receive each of the four laser beams. The lens may be positioned to direct each laser beam, of the four laser beams, toward the respective optical output of the optical device. The optical device may include an optical isolator to receive each of the four laser beams.
