Some years after the introduction of our small 337i nitrogen laser with its sealed plasma cartridge, customers started requesting a special OEM version. We developed the 337i OEM nitrogen laser with low EMI and adjustable pulse energy. Performance The
337i nitrogen laser provides 4 nsec pulses at 337 nm in the UV. The
pulse energy can be adjusted Straight-Forward Operation No alignment is necessary as the resonator mirrors are mounted on the plasma cartridge and aligned in the factory. No gas or cooling connections are needed. No warm-up time is required. The laser is ready to operate when the system is turned on. Modular Design The polymer encapsulated plasma cartridge module includes all the components that deteriorate over time. That is, the field replaceable unit incorporates the energy storage capacitors, the spark gap switching element, the plasma tube with factory aligned resonator mirrors, the electrodes, and the preionizers. Once replaced, the user regains 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 or two years, whichever occurs first. Options Our new fiber optic coupler and modular holders for filters, attenuators, energy meters, and other optical components give the design engineer more flexibility.
* Due to our corporate policy of continuous improvement, specifications are subject to change without notice. The 337i OEM laser does not comply with the Center for Devices and Radiological Health (CDRH) regulations in regards to time delay, remote interlock and warning labels. Please note that this laser can only be sold for OEM use and the equipment in which the laser is being used must, as a unit, comply with CDRH regulations.

over
the range of 150 to 200 µJ resulting in a peak power of 36 to 50 kW
and an average power of 3 to 4 mW at 20 Hz. The pulse repetition rate
can be varied from 1 to 20 Hz. The laser is externally triggered with
a TTL pulse. Reliable firing allows synchronization of the laser and
other timed events. Our fixed electrode and discharge stabilizing preionizers
result in constant pulse shape and good pulse to pulse stability. Low
EMI means the laser can operate side-by-side with computers and sensitive
electronics.
