BCC is proud to have hundred of N₂ - Lasers in operation, serving the needs of scientists in research and industry .

The BCC nitrogen lasers use a novel discharge circuit which offers a number of distinct advantages over the conventional striped-line designs . Solid state storage elements and a new type of pre-ionization are used instead of the large area capacitor plates to produce a compact laser discharge head and reproducible laser pulses of nanosecond and subnanosecond duration .

The high peak power in the UV, the short Gaussian pulse and the high repetition rate are only some of the character features of the N₂ - Laser which allows new applications . Such examples are : photochemical researches, pollution control, life time measurements into the subnanosecond range, Raman spectroscopy and medical and biological researches, LIDAR systems .
