Subject: Talk on broadly tunable parametric sources

Dear All,

Dr. Ian Lindsay from the University of Bristol will be visiting our group on Monday and will give a talk about his research.  You are all welcome to attend.  The talk will be at 3.30pm in the large meeting room on level 5 with tea and coffee afterwards.  Details of the talk are below.

Regards,

Broadly-tunable parametric sources for nanoscale imaging in the mid-IR

Abstract: Scattering-type Scanning Near-Field Optical Microscopy (s-SNOM) is maturing rapidly as a technique for optical imaging of surfaces with nanometre resolution virtually independent of wavelength.  In particular, s-SNOM in the mid-IR offers the possibility of recording FTIR-like spectra with spatial resolution hundreds of times below the diffraction limit.  However, laser sources limitations hamper further development of the field.  Broadband sources in this region currently suffer from relatively low irradiance while narrow-band sources with broad tuning ranges have limited availability.  Here, I will describe the development of a parametric source operation in the 3-4µm region and electronically tunable over hundreds of wavenumbers on millisecond timescales and its application to s-SNOM.
