Coherent radiation from a nitrogen laser

Coherent radiation from a nitrogen laser

A spatially coherent oscillator at 337 nm was made by placing a nitrogen discharge inside an unstable resonator of high magnification. An energy of 205 μJ was achieved, with 100 μJ in a diffraction-limited spot. The diffraction-limited coherence could be maintained during amplification to 1.0 mJ in...

Zusammenfassung:A spatially coherent oscillator at 337 nm was made by placing a nitrogen discharge inside an unstable resonator of high magnification. An energy of 205 μJ was achieved, with 100 μJ in a diffraction-limited spot. The diffraction-limited coherence could be maintained during amplification to 1.0 mJ in a second discharge.
