Red 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.  Make sure you answer these questions before buying any ultrafast amplifier, and future-proof your system!

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™ 1 kHz thru 5kHz

• 2.6mJ at 1kHz repetition rate
• 1.6mJ at 3kHz repetition rate
• Real time adjustment from 1-3kHz with no optical realignment
• Sub-25fs up to 50fs pulse duration: user-adjustable

Dragon™5 kHz thru 15kHz

• 1.5mJ at 5kHz repetition rate
• 1mJ at 10kHz repetition rate • 500uJ at 15kHz repetition rate
• Real time adjustment from 5-15kHz with no optical realignment
• Sub-25fs 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™ 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
• The Dragon™ is shipped with the customer’s preferred pulse duration: sub-25fs,
sub-30fs, or 100fs.
• Comprehensive industry-leading software control using KMLabs Dragonmaster

Dragon™ Pump Lasers:

KMLabs selects the optimum pump laser(s) for a particular application from one of a range of vendors.  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.
