VPSL™​ – Virtual Point Source Laser


Circular beam with diffraction-limited performance and low divergence in a standard package

Blue Sky Research’s VPSL™ laser diode sources integrate the Company’s patented µLens™ technology with a standard laser diode to generate a high power, low-divergence, circular, diffraction-limited beam. The µLens™ is mounted directly in front of the diode’s emitting edge, capturing nearly 100% of the diode’s power, circularizing the beam and correcting any aberrations, all in a single step. Because of these unique beam qualities, VPSL™ have demonstrated, for example, over 80% coupling efficiency in the visible range, into a single-mode fiber optic — up to twice that achieved by multi-macro-optics with standard laser diodes.

The design complexity of customer systems is reduced in most applications by replacing multi-optical-element diode systems with a VPSL™ and typically a single correcting lens. In fact, for many applications, no additional correcting optics is required at all. The VPSL™ can reduce cost, as well as deliver more usable power. VPSL™ are packaged exactly the same as a standard laser diode. The µLens™ is only apparent by the way it transforms and corrects the beam output. VPSL™s are available in standard 5.6mm and 9mm TO packages, allowing for direct use in a wide variety of applications.
