This OEM nitrogen laser incorporates technology developed in a series of contracts to supply a space hardened laser for the International Space Station.

Performance

The 337-Si OEM nitrogen laser emits pulses of 4 nsec in duration at 337 nm in the UV with a pulse energy of 300 µJ. Peak power is 75 kW and the average power is 3 mW at 10 Hz. The pulse repetition rate can be varied from less than one pulse per second up to 10 Hz. Low EMI enables the 337-Si laser to operate side-by-side with computers and sensitive electronics.

Beam Quality

The output of the 337-Si OEM laser is near-diffraction limited producing a collimated beam. The excellent homogeneity of the beam is shown in the beam profile. This beam can be focused to better than a 3 µm spot producing very high peak power and an energy density of 4.5 kJ/cm2.

Straight-Forward Operation





The 337-Si OEM laser is air-cooled and incorporates our patented, sealed plasma cartridge. No hookups for flowing gas or coolant are required. No alignment is necessary as the laser resonator optics are factory aligned and secured to the plasma cartridge. The laser needs no warm-up. Simply connect 24 volts and a trigger through the D-sub connector. The 337-Si is ready to go at system startup.		  

Modular Design

The laser plasma cartridge module is polymer encapsulated and includes the energy storage capacitors, the spark gap switching element, the plasma tube, the electrodes, the preionizers, and the resonator mirrors. In other words, this field replaceable unit incorporates all the laser components that are subject to deterioration with usage. Replace the cartridge; get 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.
