Since their commercial introduction in the mid-1970’s, nitrogen and dye lasers have established themselves as powerful tools for applications that require high-energy, pulsed, monochromatic radiation. Unlike most lasers, the nitrogen laser offers simple, trouble-free operation at an affordable price, and it is an excellent source for UV light at 337 nm with high peak power.
Nitrogen lasers are excellent sources for general spectroscopy, laser-induced fluorescence and photochemistry, as well as in teaching laboratories. Because of their tunability, dye lasers may be used for a large variety of applications in the UV-visible region. For experiments in the life science laboratory, nitrogen and dye lasers can easily be fiber-optically coupled to a microscope.
When pumped by nitrogen lasers, dye lasers are tunable over a wide spectral range from 360 to 990 nanometers. Dye lasers equipped with frequency doublers are even tunable in the deep UV region from 235 to 345 nm.
We at OBB Corporation have been involved in the development of commercial nitrogen and dye lasers since 1987, and this technology has undergone continual improvement since that time. OBB Corporation has pioneered a whole new laser technology that provides high power and trouble-free operation at a low price. There simply is no other tunable pulsed nanosecond laser commercially available that is this easy to use or affordable!
The Finest Nitrogen and Dye Lasers in the Industry
Nitrogen and dye lasers from OBB have excellent performance specifications, they are remarkably reliable, and they are extremely easy to use!
A dye laser is always used with a nitrogen laser and a frequency doubler is always used with both a dye and a nitrogen laser. Many assume that the precise optical alignment of such high performance components would be a frustrating process. Quite to the contrary: the OBB laser family is made to fit together easily. The construction of the cabinets of the nitrogen and dye lasers and the frequency doubler are identical, and the acceptance criteria are very forgiving. By simply placing the cabinets together, optical alignment is assured. It couldn't be simpler.
How rugged are OBB’s lasers? The Naval Ocean Systems of the Public Works Center in Jacksonville, Florida, has one in their portable laboratory. This sophisticated lab on wheels is used to probe soil for petrochemicals and other pollutants, and it has been traveling all over the country for several years. OBB’s family of lasers include:
Model OL-4300 Nitrogen Laser
The pulsed gas laser that set the industry standard is extremely reliable, economical and easy to use, and it requires only an inexpensive tank of nitrogen gas to operate—no costly cartridges to replace, no frequent servicing or fine-tuning.
Model OL-401 Dye Laser
Littrow cavity, continuously tunable from 360 to 900 nm, at an economical price.
Model OL-402 Dye Laser
High power and ultra-high resolution tunable output. Model OL-403 Frequency Doubler — Extend laser output into the deep UV region, from 235 to 345 nm.
