Nitrogen Lasers are excellent sources for general spectroscopy, laser-induced fluorescence and photochemistry
Model OL-4300 Nitrogen Laser
OBB’s Model OL-4300 Nitrogen Laser delivers a crisp pulse at 337 nanometers with a hefty 2.4 megawatts of peak power. With a pulse width of 1 nanosecond, that results in a pulse energy of 1.45 millijoules. As an excitation source or a pump for a dye laser, the OL-4300 has no peer. And you don’t have to be a “laser expert” to use the OL-4300—you'll get the specified power with the specified pulse characteristics the first time and every time. No tweaking is needed to coax the expected performance from the OL-4300.
Operation is simple and convenient. Turn on the power, purge with nitrogen for 5 seconds, and OBB’s OL-4300 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 OBB’s OL-4300. 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. With a rate of 10 Hz and a use time of 4 hours per day, a typical tank of nitrogen will last about five weeks. There is even a built-in gas-flow interlock that automatically shuts the laser down if the gas supply is interrupted.
The repetition rate may be varied from 1 to 20 Hz; OBB’s OL-4300 may also be fired manually for a single laser pulse. OBB’s OL-4300 can be synchronized to external instruments in a variety of ways. A sync pulse is available 1 microsecond before the laser fires. OBB’s OL-4300 can also be triggered by an external signal. For precise event triggering, OBB provides an optional Optical Trigger which consists of a beam splitter and fast-rise-time photodiode.
