CHAMELEON™
Widely Tunable,
Hands-Free, Mode-Locked
Ti:Sapphire Laser
Chameleon is the first single-box, hands-free ultrafast laser to tune more than 210 nm. With its
patent-pending MRU-1000 miniature air recirculator, Chameleon can tune effortlessly through
atmospheric water vapor absorption lines without an external purge.
Featuring the Power Pulse™ system, which uses our patent pending, dispersion balanced tuning
mechanism, Chameleon’s output power and pulse width is optimized automatically at all wavelengths. Incorporating the field-proven solid-state Verdi™ laser as its pump source, Chameleon is
among the most efficient and reliable - and lowest noise - ultrafast lasers available. This blend of
features makes Chameleon the laser of choice where widely tunable hands-free operation is needed.
Chameleon is ideally suited to a wide range of applications, including multi-photon excitation
microscopy, time-resolved photoluminescence, non-linear spectroscopy, fluorescence upconversion,
quantum chemistry, and terahertz imaging.
FEATURES
• Hands-free operation
• Wide 210 nm tuning range
• High power
• Superb beam quality
• Power Pulse™ system
optimizes output power
and pulse width automatically at all wavelengths
