  • IPG Photonics Corp.

BioPhotonics
Jan 2013
Fiber laser maker IPG Photonics Corp. of Oxford, Mass., reported another double-digit profit and revenue growth, this one for the third quarter of 2012, which ended Sept. 30. Profit increased to $42.4 million, up 29 percent from 2011’s $32.9 million. Revenue increased 21 percent year over year, from $129 million to $156 million. Once again, the increase was attributed to growth in high-power and pulsed laser sales for materials processing applications. Cutting and welding applications in automotive and general manufacturing in the US and Europe, as well as marking and engraving in consumer electronics, were the main drivers for the record performance. The company’s products also have applications in the medical field.


GLOSSARY
cutting
The process of forming a lens to a given pattern, or of cutting a piece of glass along the line of scratch.
fiber laser
A laser in which the lasing medium is an optical fiber doped with low levels of rare-earth halides to make it capable of amplifying light. Output is tunable over a broad range and can be broadband. Laser diodes can be used for pumping because of the fiber laser's low threshold power, eliminating the need for cooling.
optical fiber
A thin filament of drawn or extruded glass or plastic having a central core and a cladding of lower index material to promote total internal reflection (TIR). It may be used singly to transmit pulsed optical signals (communications fiber) or in bundles to transmit light or images.  
pulsed laser
A laser that emits energy in a series of short bursts or pulses and that remains inactive between each burst or pulse. The frequency of the pulses is termed the pulse-repetition frequency.
