SPECTRA-PHYSICS 337-i AIR-COOLED NITROGEN LASER SYSTEM - 2

SPECTRA-PHYSICS 337-i AIR-COOLED NITROGEN LASER SYSTEM The 337-i nitrogen laser emits 4 ns pulses in the UV at 337 nm. The pulse repetition rate may be varied from 1 to 20 Hz with a pulse energy of up to 150 ìJ. The laser is externally triggered by a TTL-level pulse for synchronization with other timed events. Constant pulse shape and good pulse-to-pulse stability were designed into the 337-i with our fixed-electrode and discharge-stabilizing pre-ionizers. The 337-i features our user-replaceable plasma cartridge, allowing the customer to regain the performance of a new laser at a fraction...
