In Depth: Laser Beam Size
The boundaries of optical beams are not
clearly defined and, in theory at least, extend
to infinity. Consequently, the dimensions of
laser beams cannot be defined as easily as the
…of Quantel Laser
(Bozeman, MT), notes the use of a feature in the Gentec system's beam-tracking
mode (see Fig. 1) called "relative position,"
which allows the alignment of the centroid of one laser beam to that of a second beam--handy for use with Quantel's

…De-Rated Pump Diodes
A laser is only as reliable and dependable as its components. A key active component in an OPSL
is the pump diode that performs the initial electrical power to optical power conversion. The
OPSL utilizes a near infrared InGaAs gain chip. One of the advantages…
Coherent OPSLs are based on InGaAs gain chips. That is because these are some of the most
reliable, longest lifetime diodes with the highest power characteristics. Quantum well devices
of this type can be designed to produce laser emission over a broad range in the…
