VCSEL arrays are particularly suited for such applications.". However, apart from competing with solid state lasers, the novel structure of many laser diodes in an array opens up some unique applications. Laser diodes typically have much higher electrical-to-optical (wall-plug) efficiencies than other types of lasers; in fact, they are some of the most-efficient light emitters known. For laser arrays, a set of lasers are cleaved together instead of individual ones. Their wavelengths range from 635 nm (visible red) to greater than 2300 nm and beyond, with electrical-to-optical efficiency reaching to more than 70% in some cases, notes Patterson. This is connected with the beam angle (divergence) in the two planes, XZ and YZ. For example, Princeton Optronics (Mercerville, NJ) makes arrays of vertical-cavity surface-emitting lasers (VCSELs) for illumination and other purposes.

When photons from a light engine are getting lost on their way to the microscope’s sample plane, follow this path to find the failure point(s). A spectral beam combining system is then used to convert the individually spaced beams into a single output beam. 4); using a camera, the depth is estimated from the distribution and shape of the spots. Laser diodes bars and multimode laser diode stacks are available in unmounted laser diode bars, or mounted in conductively or actively cooled packages. Diode lasers, which are usually used for low power applications, seem to give reasonable output powers when used as a diode laser array. Data transfer at 100 Gbps or greater can be achieved. The company's most powerful system produces 10 kW of output power at 975 nm; internally, it consists of five bars, each derated to 2 kW to ensure tens of thousands of hours of maintenance-free operation at or above specified power, says Gaebler. Care must be taken to place proper heat sinks to drain away the excess heat generated from these devices. The module itself emits 200 W of circularly polarized light at a 794.7 nm wavelength and a linewidth of <0.3 nm; the optically isolated beam is tolerant to 100% backreflection. Then based on the correct angular position of the grating, the beams will diffract into a single beam. Usually an external lens is used to focus the individual output beams to create a single high power output beam. Additionally, the lower-beam-quality versions are ideal for brazing and surface treatments due to the large divergence and the more distinct flat-top mode profile, especially when compared to high-beam-quality disk and fiber lasers where a relatively complex beam delivery and large focal lengths are needed to achieve the same desired effects at the workpiece. VCSEL arrays give very fast rise and fall times, typically <300 ps, and rise and fall times of <100 ps can be obtained with low-inductance submounts. Spectroscopic analysis of ZnO crystals grown by the hydrothermal method probes the semiconducting crystals to detect defects and impurities.
