Cascade™ Cavity-Dumped Ti:sapphire Laser

The Cascade™ is a single-box, 15fs, cavity-dumped high energy Ti:sapphire laser oscillator – capable of >30nJ.  KMLabs now offers the Cascade-5 with an internally integrated pump laser.  

KMLabs Cascade and Cascade-5 cavity-dumped femtosecond, Ti:sapphire lasers are turn-key, user-friendly products. The Cascade-5 includes an internally integrated 5W Spectra Physics Millennia or Laser Quantum Finesse pump laser.  The Cascade-5 also includes: an internally integrated spectrometer, power monitor, and remote motorized spectral and temporal control.  This single-box system measures only 83cm wide x 41cm deep x 14cm high.

Spanning 1kHz to 2MHz repetition rate at >30nJ, and sub-15fs, these rugged laser sources have applications in spectroscopy, microscopy, terahertz, OCT, harmonic generation, continuum generation and more. Our compact, user-friendly and economical lasers offer flexibility with simplicity.

Cascade and Cascade-5 Features:

•  15fs to 20fs.
•  Standard dumping rates: 40kHz, 80kHz, 200kHz, 400kHz, 800kHz, 2MHz
•  Option - 1kHz dumping rates: 1kHz, 2kHz, 5kHz, 10kHz, 20kHz, 50kHz, 100kHz
•  Dumping rates are user-selectable in real time
•  Mode-locked operation: 80.5MHz (with cavity-dumping electronics disabled.)
•  Centered at 780nm to 810nm.
•  >30nJ per pulse when cavity-dumped, or >3nJ in mode-locked operation.

The Cascade can be operated in either the cavity-dumped mode providing >30nJ at a range of repetition rates up to 2MHz, or the dumping may be electronically disabled, allowing 80.5MHz modelocked operation with >3nJ per pulse.

The Cascade is an excellent source for simple white light generation, achieved via fiber broadening.

Cascade Accessories:

•  EPPR: Prism pair for extra-cavity dispersion compensation of the Cascade.
•  PER-R-532: Polarization rotating periscope for rugged pump delivery.
•  PER-M-532: Polarization maintaining periscope for rugged pump delivery.
•  PER-ENCL: Simple enclosure and beam tubing for the KMLabs periscope.
