Credo High Repetition Rate Dye Lasers

The Credo-YHP and Credo-Pulseo high repetition rate dye laser systems build upon the designs of the popular Cobra Pulsed Dye Laser series. German engineered by our partner firm Sirah GmbH for precision, stability and reliability, the Credo dye laser systems have an optimized low threshold cavity and optional doubler resulting in a sophisticated and compact system—ideal for laser induced fluorescence and combustion studies.

The Credo systems offer:

  • Top mount adjusters for easy alignment. The top cover simply flips up and the adjusters can be accessed from both sides of the laser.
  • Optimized oscillator design to minimize pump thresholds, including cuvettes with Brewster angle windows, and a high efficiency grating-arm design.
  • Re-designed high flow rate cuvettes for efficiently replenishing spent dye in the gain region. Special care was taken to remove any impediment to flow so as to provide the smoothest, fastest transfer of dye.
  • Removable cuvettes for rapid dye changes. No need to flush out and clean the dye circulator system. The entire dye circulator system can be removed in seconds without tools and changed out for another autonomous system already filled with the dye for the next wavelength region of interest.
  • With the optional doubler, the Credo dye laser offers coverage at popular wavelengths such as 216 nm, 228 nm and 247 nm.1
  • Built-in DPSS Spectra-Physics Navigator 532-4 integrated into the laser box with the Credo-YHP model, resulting in assured alignment, smaller footprint and portability.
  • 200 kHz operation with the Credo-Pulseo model, making it the highest repetition rate dye laser available.

Just as in the Pulsed Dye Laser series, reliability is inherent in the Credo system designs. All Credo components are mounted on a solid block of low thermal expansion stainless steel, mechanically and thermally isolated from the outer laser housing. By removing virtually all mechanical and thermal stress and by using opto-mechanics optimized for easy and reproducible operation, the Credo lasers achieve a wavelength resettability for the oscillators of <5 pm, a limit set primarily by the laser’s spectral resolution.
