High Power – Narrow Linewidth UV/Blue Diode Laser

Various linewidth sensitive applications
share the same requirements with respect
to lasers: best beam quality, high power,
blue/violet wavelength and, on top of
that, a narrow linewidth. Until recently,
customers were forced to decide between
13 mW at 405 nm with superb coherence
length (up to 100 m) and 120 mW at
short coherence length (some microns). If
neither option was acceptable, they had
to resort to bulky gas lasers.
Best of Both Worlds
For the very first time, the new iWave
comprises all requirements, offering a
unique approach based on TOPTICA's
proprietary know-how in providing
narrow linewidth diode lasers:
· Permanent narrow linewidth
(< 0.08 nm ^ 5 cm-1 resp. 150 GHz)
=
for high resolution or contrast
· High power (50 mW @ 405 nm)
· Diffraction-limited beam (TEM00)
to achieve focus diameters
in the sub-micron range
Typical applications are Raman microscopy of non-fluorescent specimen or

simply any beam propagation setup
with linewidth-sensitive beam deflection
(e.g. AOD).
Matching OEM Requirements
Based on the matured iBeam series, the
iWave achieves MTBF values of several
thousand hours. Hands-off operation is
the nature of the unique iWave. Operators
receive full remote control via the RS 232
interface. A circular beam diameter of
approximately 1 mm eliminates the need
for telescopes when switching from gas
lasers to the convenient iWave. Finally,
the excellent power and beam pointing
stability emphasize its position as a OEM
laser source.
Evolution
The iWave is available in a 375 nm and
a 405 nm version, further wavelengths
are soon to come (e.g. 445 nm or
488 nm). TOPTICA already offers
narrow linewidth diode laser systems for
Raman microscopy in the near infrared
spectrum (XTRA, dfBeam). Now the
iWave complements this product family
and supports both existing and new
OEM customers.
