The diode laser offers remarkable laser beam quality with
high brightness and high optical power density. The CW optical power of
up to 1000 W is delivered through various fibres with small fibre core
diameter from 100 µm to 600 µm. Small numerical aperture of 0.22 yields
the perfect beam source for your application.
All systems are also available with
power supply
and/or
cooling unit.
We can offer you our fibre-coupled laser systems with the
wavelengths of 808 nm, 915 nm, 940nm and 980 nm.
