Nanosecond zero-order pulsed Bessel beam generated from unstable resonator based on an axicon
Unstable resonator Axicon Zero-order Bessel–Gauss beams
2013/7/2
We present what we believe the first experimental observation of a nanosecond zero order pulsed Bessel beam generated from an unstable resonator based on an axicon. The field distribution at the outpu...
Dependence of Bessel Beam Characteristics on Arrangement of Optical Axes of Axicon and Source Beam
Bessel beam Axicon Optical axis
2009/6/8
The Bessel beam (J0 beam) has potential for use in laser micro fabrication. We analyzed numerically the characteristics of a J0 beam at different distances between the optical axes of the Axicon and t...
The Vector Analysis of the Optical Resonator with the W-axicon for the Coaxial CO2 Laser
Optical resonator W-axicon, Axicon Toric mirror
2009/6/1
A resonator using w-axicon and axicon mirrors for a double coaxial electrode discharge CO2 laser is analyzed using the vector field, iterative reflection method. A uniform ring-shaped output mode is e...
