Blue Sky Research's VPSLaser(TM) laser diode sources integrate
the Company's patented µLens(TM) technology with a standard laser
diode to generate a high power, low-divergence, circular,
diffraction-limited beam. The µLens(TM) 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, VPSLasers 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 VPSLaser and typically a single correcting lens. In fact, for
many applications, no additional correcting optics is required at
all. The VPSLaser can reduce cost, as well as deliver more usable
power. VPSlasers are packaged exactly the same as a standard laser
diode. The µLens(TM) is only apparent by the way it transforms and
corrects the beam output. VPSLasers are available in standard
5.6mm and 9mm TO packages, allowing for direct use in a wide
variety of applications.
