Homogeneous Beam Profile in Pulsed Laser Diodes
PLDs with Microoptics or Fiber PigtailsHomogeneous Beam Profile in Pulsed Laser Diodes
Inexpensive, energy saving, and easy to use – laser diodes present a viable alternative
to conventional lasers. As semiconductor lasers they have a worse beam characteristic
than solid state lasers. Therefore, LASER COMPONENTS offers different concepts to
shape the beam of pulsed laser diodes.
Pulsed laser diodes with integrated microoptics reduce the divergence of the fast axis
to 5 or 10 mrad. LASER COMPONENTS Canada mounts the so-called fast-axis colli-
mation lens, FAC, directly in front of the laser diode chip. Both a PLD and an FAC lens
fit together into a tiny, hermetically-sealed TO-18 housing. The housing can withstand
acceleration rates of > 1000 g/ms; thus, it meets the standards set by military techno-
logy where the components are used for distance measurement.
An almost homogeneous beam distribution in laser diodes can be achieved by mixing
the modes in an optical fiber. LASER COMPONENTS has developed pulsed laser di-
odes with a fiber pigtail that reach an optical output power of up to100 W. They are
ideally suited for medical applications in which a high amount of peak power must be
delivered to a point as loss-free as possible.
LASER COMPONENTS‘ strengths include the quick and inexpensive development of
customer-specific pulsed laser diodes - special customer requests are implemented with
pleasure.
