TEC 42 Nanosecond
Pulsed Laser Series: CAT
Excellent with integrated microprocessor
controller
Description:
The TEC 42 diode laser system is designed for pulsed operation
of high power diode lasers. Pulse width can be changed from 5ns up to
100ns. Repetition rates can be varied from 16kHz up to 67MHz. The operation
parameters can be preset via a RS232 connector from any laptop
computer.
Target application is time resolved fluorescence spectroscopy. Please
contact us for NIR diode laser matching fluorescence dyes which have been
developed for specially for us.
Layout:
We have designed
our TEC 42 pulsed diode laser system for simple handling and for easy
operation by non-scientists. The internal microcontroller which operates the
laser pulser can be accessed from any laptop computer for setting the operation
paramters. The electrical pulsewidth which operated the diode laser can be
changed digitally in steps of 5ns. The repetition rate can be preset in steps of
1MHz. The robust and compact design enables the Cat Series laser for a wide
field of applications.
Benefit of
NIR Diodes in Fluorescence Spectroscopy:
Fluorescence spectroscopy
is a well developed detection method in the field of biomedical science. Laser
fluorescence dyes have developed since the availability of Ar-Ion and
frequency doubled Nd:YAG lasers in the 70s. Typical excitation
wavelength of laser fluorescence dyes are in the green, blue and near UV
regime. Ar-Ion and Nd:YAG laser systems are bulky and expencive in
comparison with diode lasers. Diode lasers cover the red, NIR and recently
the near UV spectral range. Our goal is to provide a matching pair of NIR diode
lasers together with a NIR sensitve fluorescence dyes.
NIR Fluorescence
Dyes:
Sacher Lasertechnik Group and Squarix GmbH have a close
cooperation for deloping matching fluorescence dyes for application in
biomedical science. NIR fluorescence dyes can be easily detected by standard
camera systems since they are operated by silicon detectors.
