Tang Y, Ross IN, Hernandez-Gomez C, New GHC, Musgrave I, Chekhlov OV, Matousek P, Collier JLet al., 2008, Optical parametric chirped-pulse amplification source suitable for seeding high-energy systems, Optics Letters, Vol: 33, Pages: 2386-2388

A short-pulse source based on optical parametric chirped-pulse amplification (OPCPA) technology has been developed with properties that make it a suitable seed for a high-energy OPCPA system. This source generated a diffraction-limited pulse at 910 nm with a full bandwidth of >165 nm and a spectrum having a transform-limited pulse duration <10 fs.

We establish the connection between a paper by Kartner et al. (F.X. Kartner, D.M. Zumbuhl, N. Matuschek, Phys. Rev. Lett. 82 (1999) 4428) entitled "Turbulence in mode-locked lasers", and earlier work on the role of noise in mode-locked laser systems. We present numerical results that broadly support the analytical results of Kartner et al.

New GHC, 2007, Theory of pulse compression using aperiodic quasi-phase-matched gratings, Journal of the Optical Society of America B, Vol: 24, Pages: 1144-1149

A simple treatment of pulse comrpession in second harmonic generation based on the use of an aperiodically-poled noninear medium is presented. Particular emphasis is placedon the conditions that must be satisfied if the process is to work efficiently. The possible extension to the case of optical parametric amplification and oscillation is considered.

Ross IN, New GHC, Bates PK, 2007, Contrast limitation due to pump noise in an optical parametric chirped pulse amplification system, Optics Communications, Vol: 273, Pages: 510-514

The contrast ratio of the recompressed output pulses in an optical parametric chirped pulse amplification system can be limited to temporal noise on the pump pulse. We present a simple analysis which can be used to estimate both the contrast ratio of this background noise and the duration of its pedestal. The estimated values compare well quantitatively with values derived using a more accurate computer simulation code.
