Pumped by a Quanta Ray^® Nd:YAG laser, a Sirah dye laser is the cost-effective and versatile source of laser light across a broad spectral range.
High-performance pulsed dye lasers are a robust and inexpensive solution for applications that require a narrow-band, high-energy, tunable source. The Sirah dye laser design incorporates state-of-the-art technology, including a precision direct-drive sine bar mechanism, interchangeable dye cells, and narrowband tunability.
Frequency doubling and mixing options extend the tuning range from 200 nm to 4 mm. The Sirah dye laser series combines with a Quanta-Ray INDI, LAB or PRO series Nd:YAG laser for a complete system.

Features

Three basic models feature a modular design
Tunability with linewidths down to 0.03 cm-1 from 330-740 nm using a single set of gratings
Short oscillator results in lowest ASE
Conversion efficiencies of up to 28% with output energies as high as 260 mJ/pulse at 570 nm
Interchangeable dye cells and dual wavelength pump optics (for 355 and 532 nm)
Repetition rates as high as 100 Hz
Integrated doubler for second-harmonic generation
Third-harmonic generation (down to 205 nm) and difference frequency mixing (to 4 mm) available
Optogalvanic calibration device
Active Wavelength Control stabilizes absolute wavelength to <5 pm
Windows-based software and LabVIEW (a product of National Insturment) drivers
