Swift™ Robust, Sealed-box Ti:sapphire Laser Oscillator
Based on the pioneering, time-tested optical architecture of the ultrashort-pulse Ti:sapphire lasers that KMLabs has manufactured for over 15 years, the Swift offers a radically new, robust mechanical design. With a sealed, temperature-stabilized enclosure, it has excellent stability even in challenging environmental conditions, and requires no re-alignment.The Swift includes: integrated pump laser, spectrometer, power monitor, laptop control computer, electronic pulse-train outputs, and a re-circulating water chiller. Its fully computer-controlled user interface enables easy tuning of the bandwidth and center wavelength. The Swift is available with a wide range of output power levels, from the economical Swift-3 to the high power Swift-10.

Swift Electronic and Computer Control:
Full
computer control of the spectrum and bandwidth is included with
every laser system. Both of
the prisms are individually
controllable by toggling a single, USB control knob. This knob
provides fine-touch adjustment, making it easier than ever to
produce the specific spectrum that you desire.
Every Swift also includes an electronic TTL pulse train signal and an
adjustable, divided TTL signal. The divided signal provides a
synchronized pulse train with a repetition rate as low as ~2MHz.
This is useful when synchronizing electronics to your laser. For
example, 2MHz is within easy triggering range of standard delay
generators.
A laptop control computer is included with every Swift laser
system. Pre-installed control software allows users to
monitor the output power and spectrum measured with the
integrated spectrometer.
Benefits of Prism-based Dispersion Compensation:
Intra-cavity prisms provide control of your spectrum - the
bandwidth, the center wavelength, and even some control of the
spectral shape. Without prisms (i.e. with chirped mirror
compensation) the user has no control of this parameter space,
without replacing optics.
Bandwidth requirements differ by application. With a
prism-based femtosecond laser, narrow or broadband operation is
available from a single laser. By simply translating one prism,
bandwidth can be varied by a factor of two or more. A laser
without prisms produces a fixed bandwidth, so the only option
for varied bandwidth is to implement lossy extra-cavity spectral
components. So, in a cavity without prisms there is significant
energy loss when narrowing the spectrum. In a prism-based
cavity, pulse energy will not decrease as the spectrum is
narrowed.
