A new set of asymmetric modes was recently revealed in a Xe slab laser with pronounced lens effects originating from gas heating in the discharge. The appearance of these modes is a threshold effect. Their domain of existence in the Xe laser is discu

A simplified six-port reflectometer design for the high power radio frequency regime is demonstrated. First a new calibration method for the often-used six-port reflectometer design is presented, where one of the signals is proportional to the forwar

In this article we have, for the first time, performed a series of lifetime tests for the continuous wave radiofrequency-excited atomic xenon laser in the 1.7–3.9 μm regime. Different constructions and electrode materials are used to investigate t

Transverse optical modes for an RF excited Ar-He-Xe laser are studied both experimentally and theoretically. A diffraction model for a waveguide with a nonsaturable gain and refractive index gradients placed between two plane mirrors is formulated. T

With respect to the propagation of a laser beam a slab-shaped laser medium may be considered as a waveguide in the transverse direction (narrow spacing) and as free space in the lateral direction (broad area). Using a common procedure of separation o

Research interest in the Ar-Xe laser has been strengthened considerably because this laser now produces output powers at the level of Watts and is becoming the most promising light source in the wavelength region of a few microns. The lasing occurs o

It is shown that the formation of a negative gas lens in a waveguide gas laser of medium pressure can break the symmetry and the number (classification) of waveguide modes. The violation of symmetry can be caused by imperfect waveguide construction o

Repetitively pulsed lasing with a high repetition rate of 10 — 20 kHz is obtained for the first time in the near-IR region from Xe atoms excited by a non-self-sustained dc discharge with preionisation by high-voltage pulses. For an active medium wi

For the first time a continuous wave RF pumped atomic xenon laser was operated in a two mode regime. Simultaneous generation on two orthogonally polarized longitudinal modes was observed in the range from 0.5 to 145 MHz close to the maximum possible
