摘要： A high-power, short-wavelength fiber laser device combines the known advantages and well-developed technology of long-wavelength fiber lasers with the concepts of both non-linear frequency doubling and non-linear sum frequency mixing to generate visible blue laser light at a wavelength of about 427 nm. The device includes a thulium fiber laser emitting light at a wavelength of 1900 nm, and an erbium fiber laser emitting light at a wavelength of 1550 nm. The light from each of the fiber lasers is frequency doubled in respective non-linear converters, resulting in respective light sources at 950 nm and 775 nm. The resulting 950 nm and 775 nm light is combined and mixed in a non-linear sum frequency mixer to produce a single short-wavelength beam of light having a wavelength of about 427 nm.

摘要： A portable laser head has a single-piece holder configured with a plurality of spaced-apart nests. The nests are arranged to receive at least a non-linear frequency converter, a V-shaped beam splitter and a dump collimator. Alternatively, the holder has multiple nests configured to receive an input collimator and output focusing optics unit in addition to the non-linear frequency converter, V-shaped beam splitter and dump collimator. The holder is characterized by small dimensions allowing for self-alignment of the above-referred components.

摘要： An assembly for distributing laser energy is provided that is formed using a compact rigid housing with a sealed beam path contained therein. The assembly employs a monolithic housing with modular collimator and mirror switching components installed therein to reduce its size while maintaining a sealed beam path thereby reducing the possibility of contamination of the beam path. Other than the optics and mirror, there are no elements of the distribution device contained within the beam path. In one embodiment, the assembly distributes incoming energy from a single source to one or more outputs. In another embodiment, the assembly operates as a beam combiner to direct energy from one or more sources to a single output.

摘要： An epoxy-free collimator assembly is configured with a ferrule and a lens operative to move within an outer case to a desired position therebetween. The collimator assembly further has an aligning component made from soft, malleable material which is capable of filling out the radial space between the ferrule and case so as to spatially fix the aligned fiber held in the ferrule and lens in the desirable position.

摘要： A mirror positioning assembly for use in beam switching is provided that employs a novel arrangement of the mirrors and the motors to selectively position the mirrors. The assembly is installed into the housing of an assembly for distributing laser energy where the mirrors are contained within the beam cavity and the remainder of the assembly is outside of the housing. The assembly is received in a port within the housing in a manner that allows 360° of rotational adjustment so that the mirror can be carefully aligned to insure near lossless distribution of the beam energy as it passes through the device. This arrangement keeps the electronics, motors, bearings and adjustments of the mirror switching external to the beam cavity herby reducing the number of potential contaminants contained therein.
