Demonstration of CW mode locked Cr:forsterite laser using self-shortening and transverse mode degeneracy driven mode locking

Abstract

This paper reports a nearly Fourier transform limited CW mode locked Cr:forsterite laser at 1282 nm, with 131 fs pulse duration, based on self-shortening and transverse mode degeneracy (TMD) driven mode locking, operating near the point of fourth-order TMD. The cavity employs a combination of instantaneous intensity driven self-shortening, and operation on the right side of the fourth-order TMD, to generate the self-amplitude modulation necessary for self-mode locking.

Analysis of the pulse widths on radiation properties from an electron driven by intense elliptically polarized laser

“…The process of generating radiation is a linear process.With laser intensity 0 1 a  , nonlinear Thomson scattering will occur. In nonlinear Tho-mson scattering, due to the high laser intensity, many nonli-near phenomena occur in the scattered light, such as photoio-niz-ation [15], high order harmonics [16], and so on.At the same time, the development of laser technology has also promoted the technological development in various fields, such as: nonlinear Thomson scattering applied to biomedic-ine, atomic physics and so on the use of X-rays and gam-ma rays. Despite the rapid development of laser technology, the influence of laser pulse width on electron electromagnetic radiation is still not so significant.…”
