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

Blue Sky Research's CircuLaser™ 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, CircuLasers 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 CircuLaser and typically a single correcting lens. In fact, for many applications, no additional correcting optics is required at all. The CircuLaser can reduce cost, as well as deliver more usable power. Circulasers 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. CircuLasers are available in standard 5.6mm and 9mm TO packages, allowing for direct use in a wide variety of applications.
