PULSED DYE LASERS

  • Wide wavelength coverage from 190 nm to >11 µm
  • Spectral linewidths <0.03 cm-1 with no intra-cavity etalon
  • User-friendly software fully LabVIEW enabled

Pulsed Dye Lasers

Spectra-Physics’ state-of-the-art pulsed dye laser systems are German engineered by our partner firm Sirah GmbH for precision, stability and reliability. At the heart of the laser system is a grazing incidence resonator designed to utilize the grating’s dispersion twice per oscillator round-trip, ensuring narrow linewidths with low ASE. An optional second grating can be added to the resonator for ultra-narrow linewidths below 0.03 cm-1 at 570 nm. The resonator allows narrow-line tuning over a broad tuning range without the need for an intra-cavity etalon or grating change, thus simplifying the measurement process without sacrificing performance.

The pulsed dye laser family includes options such as grating lift, removable cuvettes, touch screen remote control box, reversible cover, “look-up-table” or auto tracking frequency conversion units, kinematic pump mirror blocks, open source software and CAN bus communications, making these dye lasers the most versatile, technologically advanced lasers on the market.

Cobra - Entry level narrow linewidth nanosecond dye lasers

Spectra-Physics’ pulsed dye laser systems are available in three models that differ mainly in their output energies and the availability of accessories such as harmonic generation and wavelength separation. The Cobra, featuring a full range of oscillator choices and a single preamplifier stage, is designed for low energy applications from 5 to 20 mJ.
