Environmental factors such as dust could affect beam quality
That said, the TruLaser Cell 8030 is also available with the TruDisk 3001 and 4001, 3and 4-kW, disk lasers, both of which provide a beam quality
of 4 mm x mrad.
The approach exploits the broad gain bandwidth to enable large numbers of fiber laser channels to be combined with near-diffraction-limited beam quality
A unique spectral beam combining process is used to combine many fiber lasers into a single beam of light that retains the high beam quality
of the individual fiber modules while reaching the 60 kilowatt mark.
As a result, other transverse modes are generated beside fundamental transverse mode which in turn degrades beam quality
of the laser .
Ross (directed energy, US Air Force Research Laboratory, Albuquerque, New Mexico) has taught laser beam quality
analysis and requirement synthesis at SPIE's Defense, Security, and Sensing Symposia, and has developed this text from those short courses.
The fibre uses a large core-to-clad ratio to reduce stress transfer to its core, maintaining laser beam quality
and improving focal ratio degradation in lasers used for cutting, welding, drilling, soldering and marking.
The exceptional beam quality
provided by high quality YAG lasers is the basis for achieving marks for easy to read identification.
It features high average green power with industry leading stability, beam quality
, pulse width and reliability.
The tests demonstrated the good beam quality
of the lasers used and the precise and low-loss merging of the individual beams.
Compared with Nd:YAG and carbon dioxide lasers, they have higher energy efficiency, better reliability, and often better beam quality
at high power.
Randel Mercer, vice president, Business Development, Ocean Thin Films, said, "Veeco's SPECTOR-HT IBD System allows us to deliver high quality optical filters to the market faster by achieving ion beam quality
films at superior deposition rates.
