The elliptical beam thermoelectrically cooled (TEC)
laser diode
modules can be specified to produce an elliptical output beam in the
range 405nm to 830nm and output powers from 0.9mW to 27mW.
The TEC
laser diode module incorporates microprocessor based
temperature control electronics, thermo electric cooler, heatsink and
fan that enable the
laser diode temperature to be controlled to a set
point temperature between +18ºC to +25ºC, (user adjustable), and
with a stability of ±0.05ºC.
This accurate temperature control, together with user adjustment
of the
laser diode drive current, enables the laser to be tuned to
a region where mode hopping and RMS noise are significantly
reduced or eliminated. Accurate temperature control also produces
excellent wavelength and power stability and cooling the
laser diode
to 18ºC significantly increases
laser diode lifetime.
All red, infrared, blue, violet and UV TEC
laser diode modules in the
range offer low and high temperature automatic shut-off protection,
analogue and digital modulation capability and safety interlock as
standard.
