Nitrogen Lasers and 350–950 nm Dye Laser Accessories - 1

VSL Series Nitrogen Lasers and 350–950 nm Dye Laser Accessories The nitrogen laser is the most economical source of highpeak- power UV laser light available. The Spectra-Physics VSL nitrogen laser series also provides a hard-to-find wavelength range for researchers with ever-changing requirements and for manufacturers with needs for consistent power and convenient operation. Designed for constant pulse shape and a good pulse-to-pulse stability, Spectra-Physics nitrogen lasers suit the needs of both OEM and research applications. A user-replaceable plasma cartridge regenerates like-new performance at end of life for a fraction of the original laser cost and a lower cost of service. The Spectra-Physics VSL nitrogen lasers produce 337 nm wavelengths and 4 ns pulse lengths. For more flexibility, the pulse repetition rate may be triggered with an internal adjustable frequency generator, or with an external TTL signal. The Spectra-Physics VSL337ND-S is a versatile laser providing up to 260 ìJ pulses at up to 30 Hz continuously, and in bursts of up to 60 Hz. The output is near-diffraction-limited and produces a collimated beam than can be focused to a <3 ìm diameter spot with an energy density of 4.5 kJ/cm2 for precise micro-dissection. It comes with a burst-mode input for gating the trigger signal, plus a sync-signal output. For precise timing requirements, it has an OptoSync TTL output derived from the detected laser pulse itself, with sub-nanosecond jitter. The VSL337ND-S laser may be used with one of the dye laser accessories from the Spectra-Physics DUO family for IR to UV tunable output. Applications • MALDI mass spectrometry • Laser-induced fluorescence • Cell ablation and micro-dissection The VSL Nitrogen Laser Advantage • 337 nm UV pulses for MALDI mass spectrometry • Up to 260 ìJ for use in a wide range of applications • Simple operation with no alignment necessary • Sealed plasma cartridge with no flowing or external gas connections required • Field-replaceable plasma cartridge lowers total cost of ownership • Built-in adjustable trigger rate and external trigger input adds versatility • Low EMI versions available for noise-sensitive measurements • Available diffraction-limited beam focuses to spots under 3 ìm • Easy integration with a variety of dye lasers with simple tunability from 350 nm to 950 nm VSL337ND-S Laser VSL337 Laser For more modest energy requirements with simple triggering needs, the Spectra-Physics VSL337 provides 120 ìJ pulses at up to 20 Hz continuously. Its low energy consumption enables operation from either an external 12 V battery, or with the supplied external voltage adapter, making it ideal for field applications. The VSL337 may also be used with one of the Spectra-Physics DYE family lasers for IR to UV tunable output. • Medical diagnostics • Materials research • Manufacturing Spectra-Physics VSL337 Nitrogen Laser

Nitrogen Lasers and 350–950 nm Dye Laser Accessories - 3

Accessories for the VSL Family of Nitrogen Lasers The Spectra-Physics DUO and DYE families of dye lasers are designed to be optically pumped by one of the VSL family of nitrogen lasers. These dye lasers produce a tunable, polarized output from about 360 to 950 nm, depending on the chosen dye and the laser model. The accompanying chart shows typical wavelength versus relative output energy for various dyes. All dye laser accessories come with a cuvette for holding the dye solution in the pump chamber, but the dye itself must be ordered separately from Exciton. In addition, the DUO series has...
