Hybrid topological evolution of multi-singularity vortex beams: Generalized nature for helical-Ince-Gaussian and Hermite-Laguerre-Gaussian modes
Yijie Shen, Yuan Meng, Xing Fu +1
A generalized family of scalar structured Gaussian modes including helical-Ince--Gaussian (HIG) and Hermite--Laguerre--Gaussian (HLG) beams is presented with physical insight upon…
Watt-level, kHz pulsed ASE source with pulse-width close to round-trip time based on Nd:GdVO4 bounce geometry
Rui Guo, Mingming Nie, Mali Gong
We demonstrate a watt-level, kHz nanosecond-pulse ASE source with its pulse-width being close to its round-trip time. The ASE uses a Nd:GdVO4 high gain bounce geometry structure wi…
Truncated triangular diffraction lattices and orbital-angular-momentum detection of vortex SU(2) geometric modes
Yijie Shen, Xing Fu, Mali Gong
We for the first time report the truncated diffraction with a triangular aperture of the SU(2) geometric modes and propose a method to detect the complicated orbital angular moment…
Sub-MHz Self-Q-switching in Nd:LuAG Laser
Guangju Zhang, Xing Fu, Yijie Shen +1
A compact pulsed Nd:LuAG laser at 1064 nm based on the self-Q-switching technique is reported, having the output power as high as 6.61 W at the incident pump power of 21.32 W, corr…
Polygonal vortex beams in quasi-frequency-degenerate states
Yijie Shen, Zhensong Wan, Yuan Meng +2
We originally demonstrate the vortex beams with patterns of closed polygons [namely polygonal vortex beams (PVBs)] generated by a quasi-frequency-degenerate (QFD) Yb:CALGO laser re…
Dual-wavelength vortex beam with high stability in diode-pumped Yb:CaGdAlO4 Laser
Yijie Shen, Yuan Meng, Xing Fu +1
We present a stable dual-wavelength vortex beam carrying orbital angular momentum (OAM) with two spectral peaks separated by a few terahertz in diode-pumped Yb:CaGdAlO4 (CALGO) las…
