The 337i OEM nitrogen laser features a sealed plasma cartridge, low EMI, and adjustable pulse energy. In a convenient OEM suitable package, the 337i operates with an external 24 VDC power supply and trigger. |
Performance |
The 337i nitrogen laser provides 4 nsec pulses at 337 nm in the UV. The pulse energy can be adjusted up to 170 µJ resulting in a peak power of 36 kW and an average power of 3 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 pre-ionizers 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. |
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 pre-ionizers. 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. |
