Red Diode Laser Modules
Featuring
Collimated / Focused Circular Beam
Features
The MiniLaseCF Family of lasers from Blue Sky Research has been specifically designed to
TM
offer superior beam qualities in a compact package for OEM applications. The MiniLaseCF products
combine Blue Sky Research’s VPS (virtual point source) lasers with high quality optics, solid packages
TM
and laser drive electronics. The circular, diffraction-limited gaussian beam from MiniLaseCF products,
either well collimated or focused at the chosen distance, is much better than the beam from a regular
diode laser module and easier to be integrated with other optics. The built-in automatic power stabilization
(APC) function provides high stability and low noise at the same time. All devices include integrated on/off
LED indicators to visually confirm module operation and simplify OEM field service operations.

Performance
MiniLaseCF products utilize the patented µlens technology to gain distinct performance
advantages over traditional LD based modules. Starting from a regular laser diode with elliptical beam,
the technology creates a virtual point source (VPS) with circular divergence beam. A high-quality
aspherical lens is then used to collimate or focus the beam, which keeps the diffraction-limited quality. A
good Gaussian profile (M2 < 1.3) and low wavefront aberrations enable the beam from the MiniLaseCF to
be collimated better or be focused into a smaller, more visible spot/target. The built-in APC function keeps
the short-term power stability for the MiniLase products less than 1.0% at 25°C. The noise is kept low at
<0.5% within 20Hz - 20MHz in short term. Properly used with a heat sink, modules have typical lifetimes,
(MTTF, Mean Time to Failure) of +10,000 hrs.
Flexibility of the design is a key concept for the MiniLaseCF products. A series of standard
products are offered as well as a great possibility of customer-specified wavelength, power, beam size or
TM
focused distance. Please consult Blue Sky Research for more details on the custom MiniLaseCF laser
module.

Beam size is the diameter measured as
1/e2
aperture at the exit aperture of modules.
The minimal spot sizes occur at the 25mm and 180mm focus distance separately for package A and B.
Increasing the focus distance will increase the spot size.
Other spot sizes and focus distances are available. Please contact BSR with any custom requests.
