The Spectra-Physics VSL-337ND-S nitrogen laser emits 4 ns pulses in the UV at 337 nm. The pulse repetition rate may be varied from 1 to 60 Hz with a pulse energy of up to 300 mJ. The laser may be triggered internally or externally. A unique feature of the VSL-337ND-S is the Optosync port, which delivers a high-speed TTL signal derived from the laser itself that results in sub-nanosecond jitter. Constant pulse shape and good pulse-to-pulse stability were designed into the VSL-337ND-S with our fixed-electrode and discharge-stabilizing pre-ionizers. The VSL-337ND-S features our user-replaceable plasma cartridge, allowing the customer to regain the performance of a new laser at a fraction of the cost. Our patented design ensures minimal downtime because no adjustments are necessary for the resumption of full-spec performance. The plasma cartridge typically maintains at least 70% of its energy for 20 million pulses. The output of the VSL-337ND-S laser is near-diffraction limited and produces a collimated beam that can be focused to a >3 mm spot of peak power with energy density of 4.5 kJ/cm². This versatile laser may also be equipped with one of its dye laser accessories, the DUO ...
