Dragon™ Ti:sapphire Laser Amplifier
The Dragon™ is the highest average power, shortest pulse, single-stage ultrafast Ti:sapphire laser system on the market, allowing real time software-controlled changes in the repetition rate, without optical realignment. Dragon series amplifier systems operate over a range of repetition rate ranges between 1 and 20kHz.
KMLabs is the world-leader in CEP-stabilized amplifier systems. Dragon series amplifiers are available as CEP-ready or fully CEP-stabilized systems.
Harmonic conversion, OPA and EUV options are now available for Dragon series amplifiers.
Shortest
Amplified Pulses Available:
Dragon: <25 or <30fs fs, up to
10 W
Single-Stage Laser Amplifier
The standard KMLabs Dragon uses multipass amplification to generate pulses that are below 30 fs in duration with up to 3mJ pulse energy, up to 10 W in average power. We also offer a simple inexpensive option to generate controllable pulse duration between sub-25 fs and sub-30 fs pulses.
Dragon-HE: <40fs 5mJ 1kHz Single-Stage Laser Amplifier
The Dragon-HE multipass ultrafast Ti:sapphire
laser amplifier is a higher energy version of the Dragon, producing
5W at 1kHz in a single stage of amplification.
The Dragon-HE combines the simplicity of a single stage system, with
the power expected from a multi-stage system:
•
5W / 5mJ at 1kHz repetition rate
•
6W / 2mJ at 3kHz repetition rate
•
Real time adjustment from 1-3kHz with no optical
realignment
•
Sub-40fs up to 50fs pulse duration: user-adjustable
Benefits of
Cryogenic Cooling:
KMLabs uses compact He-gas cryo-cooling systems or liquid He cryorefrigerator systems. These are compact, fully-interlocked, and maintenance-free and can be configured to minimize vibration for demanding applications such as carrier envelope stabilization. Read more about the benefits of cryo-cooling.
Dragon and Dragon-HE Features:
• Patented cryogenic cooling
of the Ti:sapphire crystal in a single-stage amplifier
is available exclusively through KMLabs.
•
Vacuum cryo-cell that protects the crystal using a
sealed, internal ion pump
that requires negligible user maintenance.
•
Comprehensive, fully integrated system diagnostics
make the Dragon a user-
friendly amplification system, providing
reference data for real time assistance
with spatial, spectral and
energy optimization. Multiple cameras make
alignment quick and
simple. Extensive data logs allow remote observation of
system
configuration for diagnostic assistance.
•
Beam quality can be optimized in real time, ensuring
highest efficiency OPA
performance. Greater then 40% conversion to
signal + idler has been
demonstrated.
•
The Dragon is shipped with the customer's preferred
pulse duration: sub-25fs,
sub-30fs, or 100fs (<40 or 50fs for the
HE).
•
Comprehensive industry-leading software control using
KMLabs Dragonmaster
software.
Dragon and Dragon-HE Pump Lasers:
KMLabs does not manufacture our own pump lasers, a position that allows us to select the optimum pump laser(s) for a particular application from one of a range of vendors including Photonics Industries, Coherent and Newport-Spectra Physics. We are happy to discuss the trades – performance, reliability and service support – between these different vendors. Elimination of the thermal lens via cryo-cooling allows great flexibility in the pump laser selection for optimum repetition rate, pulse energy, and noise. Cryo-cooling also provides a very simple subsequent upgrade path to a higher power single or multi-stage system. Without cryo-cooling, other vendors offer point designs which are complex or impossible to upgrade.
