PROPERTIES

FIELDS OF APPLICATION

The LDM300 series of laser diode
modules are wavelength stabilized to an
extremely narrow linewidth of <50MHz
(<10-7 relative linewidth).

These compact, high quality, laser diode
modules may be used for industrial
metrology
and
machine
alignment
applications.

Fibre coupling allows flexible installation
and separation of the electrical and optical
sections of your design.

The very narrow linewidth allows use in
interferometic applications. Thus the use
of HeNe lasers can be avoided: an
obvious advantage in power, space,
lifetime and service costs.

High quality optics and precision
adjustment provide for excellent beam
quality and very long collimation distances
of 50m and more. Customized fixed focus
distances may also be provided.

The option of choice of polarization is
unique and provides many advantages in
measurement
reproducibility
in
metrological applications.

The excellent beam quality provides for
high reproducibility independant of module
rotation. The rugged design is adapted to
industrial applications and provides for
very high pointing stability.
In OEM applications, the small size of the
source allows for simple integration.

The LDM300 has an exit beam diameter of
5mm. Smaller and larger diameters are
available on request.
