Intracavity generation of longitudinal dependant Bessel like beams
In this paper we report on two resonator systems for producing LDBLBs with arbitrary initial parameters. First resonator system is based on doublet of divergence and convergence lenses with spherical aberration. Second resonator system is based on doublet of axicon and axicon-lens. For both resonator systems the LDBLB is output of fundamental mode, but the spectral properties of obtaining LDBLBs are different. © 2009 SPIE.
