laser modules can meet your exact needs.
Patented AlignLock technology
Only Coherent allows the laser beam to be simultaneously collimated and aligned. Other diode
laser manufacturers can do one or the other, but
not…

…fiber laser design is
based on the use of diode laser bars, rather than single emitters, as the pump sources. The light from these pump bars is
introduced into the gain fiber using a beam combiner consisting of discrete optical elements. This same beam combiner
collimates the output…

Coherent Magnum II Laser Operator's Manual

laser diodes can produce beam profiles
that are far from Gaussian in shape, resulting in a beam that may
exhibit an "M"-shaped longitudinal profile with a large gap. In such
cases, it is difficult to extend the beam into a very uniform line. At
Coherent, we match each diode with…

…different VBG temperatures or laser frequencies. (b)
The spectra peaks are plotted as a function of the VBG temperature or laser frequency
detuning. The FWHM linewidth is about 3oC, equivalent to 10 GHz.
In summary, in this paper we report a diode laser array linewidth-narrowing…

picture shows the "free-running" array collimated using a standard diffraction limited quality FAC lens. The diagram on
the left shows the profile using the VHG-FAC lens for collimation.

laser system is a direct-emitting semiconductor laser.
The output beam of the diode is collimated by a high-aperture lens.
Additionally, the beam is formed by a prism pair to achieve a round
beam in the far field. A thermoelectric cooler is integrated for stabilizing the diode laser.

CW and quasi-CW lasers. Typical examples of these
are gas lasers (e.g. HeNe's, ion lasers and HeCd's),
collimated diode lasers, optically pumped
semiconductor lasers (OPSLs), collimated fiber lasers,
and mode locked solid-state lasers.
