Characteristics of high-power photopreionization-stabilized UV nitrogen lasers operating at gas pressures of up to 6 atmospheres
Abstract
A quantitative and detailed analysis is presented for the lasing properties of photopreionization-stabilized UV nitrogen lasers at pressures up to about 6 atm and specific power loadings up to 5 billion W/cu cm. It is shown that nitrogen lasers can provide specific output powers up to about 6 MW/cu cm at atmospheric pressure. A scientific basis is provided for the development of recently publicized ultraminiature (mm-size) nitrogen lasers which generate beam powers up to about 0.2 MW. Preliminary dye vapor work shows that a specified photopreionization stabilized discharge scheme will provide homogeneous plasmas at high specific pump inputs. This represents a significant step toward the development of discharge-excited dye vapor lasers.
