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.

PrecisionScan - Higher energy amplified narrow linewidth nanosecond dye lasers

The PrecisionScan is Spectra-Physics’ top-end pulsed dye laser system. Configured with three stages, the PrecisionScan provides the versatility to accommodate two main amplifiers for high-energy applications ranging from >1000 mJ of pump energy at 355 nm and >1400 mJ at 532 nm; or can alternatively house an additional frequency conversion unit for frequency doubling capabilities. Enhanced with standard dual wavelength optics, switching between 532 and 355 nm pump lasers becomes a straightforward procedure.
