Princeton Optronics Inc of Mercerville, NJ, USA, which manufactures high-power single- and multi-mode vertical-cavity surface-emitting lasers (VCSELs) and VCSEL arrays, has announced the availability of 15W red laser devices and arrays emitting at a wavelength of 650nm for medical and illumination applications.
The lasers have an efficiency of >20%, a spectral width of about 1nm and a circular beam with divergence of 18 degrees (full angle). The array has a size of 3mm x 3mm and is mounted on submounts.
Princeton Optronics says it can deliver such arrays in high volume through its high-volume manufacturing operation. In addition, it can deliver single devices and lower-power versions, as well as addressable arrays at red and other wavelengths. The firm is also able to make custom devices and arrays of other configurations and other wavelengths in red.
