Odin-II is designed to accept most commercial seed oscillators with a bandwidth of
70-100 nm and power >200 mW.
The Odin-II is the shortest pulse, highest peak
power integrated ultrafast Ti:Sapphire system
available, producing <25 fs pulses. The Odin-II
contains an internal Nd:YLF pump laser along
with the Ti:Sapphire multipass amplifier stages
and the grating stretcher/compressor; the wideband seed source (for example, the Quantronix
Ti-Light) is external.
Odin-II provides pulse energies of greater than
3.5 mJ and pulse widths <25 fs with excellent
energy stability. The Odin-II-HE produces pulses
over 5 mJ, while maintaining pulse durations of
<30 fs with superior beam quality and stability.
The multipass amplifier design uses the absolute
minimum amount of material in the amplifier,
thus minimizing the residual uncompensated
high-order dispersion typically associated with
regenerative amplifier designs. This results in
clean, pedestal-free pulses. Also the constant
number of passes in a multipass amplifier allows
energy tunability without changing the dispersion characteristics of the system.
The Odin-II multipass design, combined with
unique Pockels cell placement within the amplifier,
increases the contrast ratio while maintaining
a single pass through the Pockels cell for <25 fs
pulse generation.
Applications that require multipass amplifiers
include HHG, X-ray generation, CEP stabilization
and attosecond generation.
