Homogeneous beam profile in pulsed laser diodes

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 collimation 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 technology 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 diodes 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.
