Abstract

Pulsed laser on the transition 5d¹⁰6p²P_3/2-5d⁹6s²²D_5/2 of mercury ion HgII, which is an analog of well known laser transitions in gold and copper atoms, was studied by a double-pulse method. Experiments were carried out with discharge tubes of 4 and 8 mm bore and discharge length 30 cm with buffer gases helium and neon. It was observed that lasing in the smaller and larger tubes differs substantially. In the larger tube lasing was observed only at small time delay and never had a ring form, as it was observed earlier with smaller bore tubes. Lasing was observed at a time delay shorter than 5 microseconds but with an increase of pulse repetition rate and tube heating it disappeared. Possible mechanism of inversion formation are discussed.
