Deep ultraviolet diamond Raman laser

open access: yesOptics Express, 2011
We present a synchronously pumped diamond Raman laser operating at 275.7 nm pumped by the 4th harmonic of a mode locked Nd:YVO4 laser. The laser had a threshold pump pulse energy of 5.8 nJ and generated up to 0.96 nJ pulses at 10.3% conversion efficiency.

Thermodynamic Bethe Ansatz of the Homogeneous Sine-Gordon models [PDF]

open access: yes, 1999
We apply the thermodynamic Bethe Ansatz to investigate the high energy behaviour of a class of scattering matrices which have recently been proposed to describe the Homogeneous sine-Gordon models related to simply laced Lie algebras.

Higher particle form factors of branch point twist fields in integrable quantum field theories [PDF]

open access: yes, 2011
In this paper we compute higher particle form factors of branch point twist fields. These fields were first described in the context of massive 1+1-dimensional integrable quantum field theories and their correlation functions are related to the bi ...
