Cleanroom-Laserlab


This is an image of the laser laboratory in the cleanroom. It used to be used for ultrafast time-resolved spectroscopy, but now it is used for non-linear optics and for terahertz optics and spectroscopy. A caption for the image could be “Amplified femtosecond laser system for optical and terahertz spectroscopy”. The system s based on a “Tsunami” oscillator and a “Spitfire” amplifier, both from Spectra-Physics.   

Femtosecond lasersystem

Femtosecond lasersystem


This is an image of the lab I use for non-linear optical spectroscopy and imaging. The femtosecond laser system is based on a “Tsunami” oscillator from Spectra-Physics combined with an “Integra-C” amplifier from Quantronics. A “TOPAS-C” optical parametric amplifier allow us to tune the wavelength of the 100fs pulses from near UV to near-IR. The system is being used for non-linear optical spectroscopy and imaging of semiconductors and nanostructured materials.

Terascan 1550


This is an image of our Terascan 1550 CW terahertz spectrometer from TOPTICA. The sample compartment is enclosed and can maintain a controlled humidity between 5-95% if necessary. This is one of the workhorses for our terahertz activities. 

THz-TDS system

THz-TDS system


This is our second Terahertz spectrometer. This system is a TeraSmart pulsed terahertz spectrometer from Menlo Systems (the image is from Menlo’s website). We have just bought a “TeraImage” expansion for the system, so in the future we will be able to do automated terahertz imaging. I will send you a new image when the complete system has been set up.
