ULM Photonics offers new polarization-stabilized single-mode VCSELs with an increased output power. The new A4-PL model has an output of 1.4 mW, which is double that of the previous model.
These diode lasers are available both as a chip and in a TO housing. The emission wavelength is 855 nm ± 10 nm.
This series was primarily developed for use in a PC mouse and for trackball applications in cell phones. SM VCSELs can also be used in sensor technology.
