The VSL-337ND-S nitrogen laser sets a new standard for laser ease-of-use. The full-featured VSL-337ND-S is our high performance nitrogen laser, ideal for demanding laboratory or OEM applications. It comes fully compliant to CE mark requirements.
Performance
The VSL-337ND-S nitrogen laser emits pulses of 4 nsec in duration at 337 nm in the UV with a pulse energy of 300 µJ. Peak power is 75 kW and the average power is 6 mW at 20 Hz. The pulse repetition rate can be varied from less than one pulse per second up to 30 Hz, and up to 60 Hz in burst mode. A unique feature of the VSL-337ND-S is the optosync port, which provides a high speed TTL signal derived from the laser itself resulting in subnanosecond jitter.
Beam Quality
The output of the VSL-337ND-S is near-diffraction limited producing a collimated beam. The excellent homogeneity of the beam is shown in the beam profile. This beam can be focused to better than a 3 µm spot producing very high peak power and an energy density of 4.5 kJ/cm2.
Flexibility
The VSL-337ND-S nitrogen laser features trigger and burst input ports plus sync and optosync output ports. All of these ports are TTL compatible. The optosync port is capable of driving a 50 ohm load. These ports make it easy for the researcher to devise and implement experiments involving precise and complex timing schemes.
Turnkey Operation
The VSL-337ND-S is air-cooled and incorporates our patented, sealed plasma cartridge. No hookups for flowing gas or coolant are required. No alignment is necessary as the laser resonator optics are factory adjusted and are an integral part of the plasma cartridge.
Modular Design
The laser plasma cartridge module is polymer encapsulated and contains the energy storage capacitors, the spark gap switching element, the plasma tube, the electrodes, the pre-ionizers, and the factory aligned resonator mirrors. In other words, this field replaceable unit incorporates all the laser components that are subject to deterioration with usage. Replace the cartridge; get the performance of a new laser at a fraction of the cost!
Long Life
The plasma cartridge is warranted to maintain at least 70% of its energy for twenty million pulses.
Options
This versatile laser may also be equipped with one of its dye laser accessories, the DUO 220 or DUO 210, for obtaining tunable output from the IR to the UV. |
