HIGH POWER
Amplified Diode Lasers
An application calls for a tunable laser with
narrow linewidth, but also high power?
TOPTICA offers a family of amplified diode
lasers. Depending the requirements, the
TA pro, BoosTA and BoosTA pro can do
the job.
The TA pro is a member of TOPTICA’s pro
series and consistently follows the concept
of maximum stability and ease of use.
This product consists of a grating stabilized
diode laser and a tapered semiconductor
amplifier.
This Master-Oscillator Power-Amplifier
(MOPA) concept combines the tunability
and linewidth of the DL pro seed laser with
the high power and excellent beam quality
available from tapered amplifiers.
Master oscillator and power amplifier
are independently driven by a pair of

26

temperature and current controllers.
Patented, flexure-based mirror mounts
ensure easy coupling of the master laser
into the tapered amplifier. At the same time,
the highly stable design prevents intensity
fluctuations that might arise from beam
pointing variations. For beam shaping,
TOPTICA uses custom-made optical
components, achieving an excellent beam
profile and highest single-mode fibercoupling efficiencies.
The TA pro laser head is available as SYST
TA pro with the analog DC 110 doublestage rack system (see page 43) and as
DLC TA pro with the DLC pro, TOPTICA’s
new all digital control electronics.
In the latter version, the DLC pro 19’’ rack
includes two low-noise current controllers,
two temperature controllers, a scan control
with HV amplifier for the ECDL’s piezo and

readily comprises advanced digital locking
functions. More information on the new
DLC pro can be found on pages 41/42.
A straightforward solution to amplify
existing lasers is the BoosTA pro system,
featuring the power-amplifier of the TA pro,
along with its superior heat management
and beam-shaping optics for input and
output beams. The BoosTA pro system
comes with TOPTICA’s compact current
and temperature controller DC HP and
achieves highest output powers at low
intensity-noise.
The established BoosTA system is a
low-cost, compact amplifier module.
It combines the tapered amplifier chips
of the TA pro with electronics built into
the laser head. For the experienced
scientist it allows easy integration into an
existing setup.
