Tunable, single axial mode LiF:F2− laser
Autor: Iain T. McKinnie, Valerii V. Ter-Mikirtychev, D.M. Warrington, J.C. Diettrich
Publikováno v: Optics Communications. 204:317-322
We have developed a gain-switched room temperature single axial mode LiF:F2− laser using a coupled narrowband resonator. The resonator uses a classic four-prism achromatic beam expander/Littrow grating configuration, augmented with a dichroic mirro

Publikováno v: Optical Materials. 16:341-347
The first-order hyperpolarizabilities, β, of a number of novel merocyanine compounds bearing electron donor and acceptor groups at opposite ends of the molecules have been determined using hyper-Rayleigh scattering. The values of β increased with i

A simple, novel method for the preparation of polymer-tetherable, zwitterionic merocyanine NLO-chromophores
Autor: Iain T. McKinnie, Thomas H. Barnes, Andrew J. Kay, Anthony D. Woolhouse, Timothy G. Haskell, Graeme J. Gainsford, C. P. Wyss
Publikováno v: Journal of Materials Chemistry. 11:996-1002
A suite of polymer-ready nonlinear optical merocyanines has been synthesised and characterised. The tethering functionality—a vicinal dihydroxypropyl residue—is introduced onto the donor nitrogen of the chromophore precursor without the need for

Simple zwitterionic merocyanines as potential NLO chromophores
Autor: Iain T. McKinnie, Thomas H. Barnes, C. P. Wyss, Andrew J. Kay, Graeme J. Gainsford, Timothy G. Haskell, Anthony D. Woolhouse, Shirin M. Giffin
Publikováno v: Journal of Materials Chemistry. 11:2271-2281
A suite of zwitterionic pyridylidene-based merocyanines that contain no interconnecting π-bridge between the donor and acceptor rings has been synthesised and their second-order NLO properties evaluated largely by semi-empirical computational method

Ultrafast lasers yield X-rays
Autor: Iain T. McKinnie, Henry C. Kapteyn
Publikováno v: Nature Photonics. 4:149-151
Table-top sources that generate both extreme ultraviolet light and soft X-rays through high-harmonic generation of ultrafast infrared laser pulses look set to perform tasks previously accessible using only large-scale synchrotrons.

Observation of a thermal phase-grating contribution to diffraction in erythrosin-doped gelatin films
Autor: R.Y. Choie, Iain T. McKinnie, T.H. Barnes, W. J. Sandle, Anthony D. Woolhouse
Publikováno v: Optics Communications. 186:43-50
Dynamic laser-induced gratings were written into gelatin films doped with the xanthene dye – erythrosin B. The diffraction signal relaxation time from the transient grating was analysed as a function of the pump beam fluence and grating period. Als

Single-mode visible and mid-infrared periodically poled lithium niobate optical parametric oscillator amplified in perylene red doped poly(methyl methacrylate)
Autor: Philip Schlup, G.W. Baxter, Iain T. McKinnie
Publikováno v: Optics Communications. 184:225-230
We have demonstrated a simple grazing-incidence optical parametric oscillator (OPO) based on periodically poled lithium niobate (PPLN) capable of generating single-mode visible (619–640 nm) and infrared (3.16–3.77 μm) radiation. The single-mode
