| Abstract: | Laser beams which behave like the so-called diffraction-free beams have been generated by an argon ion laser with a new type of cavity. They have almost the same intensity distributions and propagation characteristics as those predicted for the Bessel-Gauss beams which were introduced recently. Beams corresponding not only to the lowestorder but also to higher-order Bessel-Gauss beams have been obtained. |
