RedDragon™ Ti:sapphire Laser Amplifier
The RedDragon™ offers unmatched peak/average power in < 25fs pulses.
RedDragon Series amplifier systems operate over a range of
repetition rate ranges between 1kHz and 20kHz.
Average power levels are as high as 50W, and pulse energies
as high as 20 mJ (1kHz) are available.
The RedDragon employs the
Dragon as the first stage of amplification,
and also implements cryogenic cooling in the
second amplification stage to enable
real time software-controlled changes in the repetition rate,
without optical realignment.
Harmonic conversion, OPA, and EUV
options are now available for Dragon Series
amplifiers.
By contrast, systems that employ cryogenic cooling only within second and subsequent amplification stages suffer from thermal lensing within the first stage amplification crystal, just as a non cryo-cooled single stage amplifier would. Thermal lensing within the first amplification stage introduces higher order aberrations that can be harmful for the most demanding applications. Real time changes in repetition rate or pump power offered by the RedDragon are not possible without first stage cryo-cooling.
1-5kHz example, KMLabs can provide a single sub-25fs, RedDragon laser system producing: 10.5mJ at 1kHz AND 6.8mJ at 3kHz, with no optical realignment necessary, as repetition-rate changes from 1-5kHz.
5-15kHz example, KMLabs can provide a single sub-25fs, RedDragon
laser system producing: 5.9mJ at 5kHz AND 4.2mJ at 10kHz, with no
optical realignment necessary, as repetition-rate changes from
5-15kHz.
KMLabs is the world-leader in CEP-stabilized
amplifier systems for high energy / high rep-rate systems.
RedDragon Series amplifiers are available as CEP-ready or fully
CEP-stabilized systems.
RedDragon
Features:
•
Patented cryogenic
cooling of the Ti:sapphire crystal in a single-stage
amplifier is available exclusively through KMLabs.
•
KMLabs cryogenic cooling is compact,
fully-interlocked and maintenance-free.
•
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.
•
Comprehensive industry-leading software control using KMLabs
Dragonmaster
software.
