Spectra-Physics lasers, a Division of Newport Corporation has released the Credo™-YHP high repetition rate dye laser systems built 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-YHP dye laser system has an optimized cavity with a built-in pump laser and optional doubler resulting in a sophisticated and compact system—ideal for laser induced fluorescence and combustion studies.
The Credo-YHP offers:
Built-in DPSS Spectra-Physics’ Navigator 532-40 integrated into the laser box, resulting in assured alignment, smaller footprint and portability.
• 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-YHP dye laser offers coverage at popular wavelengths such as 216 nm, 228 nm and 247 nm.
Just as in the Pulsed Dye Laser series, reliability is inherent in the Credo-YHP system design. All Credo-YHP 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-YHP laser achieves a wavelength resettability for the oscillators of <5 pm, a limit set primarily by the laser's spectral resolution.
