In 1981 when
Arnold leaves the Battelle Institute in Geneva he founded MULTILASERS in Geneva.
During four years it develops and markets nitrogen lasers producing diffraction limited beam specially designed
for the calibration of the drift chamber and streamer chambers.
More than 60
MOPALITE nitrogen lasers are used world
wide ( CERN, FERMILAB, KEK,MIT,ORSAY)
The MOPALITE
family consists of a COMPACT pulsed nitrogen laser with VERY SMALL beam
DIVERGENCE, SMALL beam CROSS SECTION and PICOSECOND PULSES.

The MOPA system
permit a 2000 times increase in brightness (W/cm2.sr) compared with a normal
TEA nitrogen laser. The extremely high brightness of MOPALITE laser is achieved by a design
feature unique among existing super-radiant lasers. Two independent laser
section are activated with a time delay of about 300 picoseconds and a special
design suppresses the optical delay line. (Patented)
The first
discharge section MO ( Master
Oscillator) is beam divergence selected and injected in to the second discharge
section PA (Power Amplifier) and polarised with a glan Thomson polariser and
injected in a second amplifier to obtain a high output power with a high spatial
coherence.
