PTI's Model GL-3300 Nitrogen Laser Photon Technology International . . The GL-3300 Nitrogen Laser delivers a crisp pulse at 337 nanometers with a hefty 2.4 megawatts of peak power. With a pulse width of 600 picoseconds, that results in a pulse energy of 1.45 millijoules. As an excitation source or a pump for a dye laser, the GL-3300 has no peer. No tweaking is needed to coax the expected performance from the GL-3300.
Operation is simple and convenient.
Turn on the power, purge with nitrogen for 5 seconds, and the GL-3300 will activate. An inexpensive cylinder of nitrogen is connected to the rear panel. Everything needed to control the nitrogen flow and pressure is built into the GL-3300. Since the nitrogen pressure is low, there is no need for any special safety precautions. Because higher repetition rates require higher nitrogen flow, gas usage is dependent on the rep rate.
