Our research is carried out in two 600 sq. ft labs on the first floor of Ghausi Hall, where we have state-of the-art laser and nonlinear optics equipment. We have a variety of laser systems available covering a wide wavelength range:
•An amplified, pulsed, high peak power Ti- sapphire laser system consisting of the following components:
1. High power, diode-pumped solid state laser, Spectra Physics Millennia V-P, >5 W of CW output power at 532 nm.
2. Regeneratively mode-locked Ti-sapphire laser, Spectra Physics 3941-M1s.1
3. kHz intra-cavity doubled Nd-YLF pump laser (to pump the Ti-sapphire regenerative amplifier), Spectra Physics Merlin LCX.1
4. kHz tunable Ti-sapphire regenerative amplifier, Spectra Physics Spitfire LCX.
This system produces 130 fs pulses, with pulse energy of 0.3 mJ per pulse, at a rep rate of 1 kHz in the wavelength range between 750 and 840 nm. The system is also equipped with a femtosecond Optical Parametric Amplifier, Spectra Physics OPA800F-0.3, which extends the wavelength range to 1.1-3.0 mm, with a pulse energy of 50 mJ. A Model SSA-F Single shot autocorrelator is available for femtosecond pulse length measurement.
•Mode-locked and Q-switched Nd: YAG laser (Coherent Antares), with an average power of 20 W at 1064 nm and 2 W at 532 nm. In ML operation this laser system has 100 ps pulse duration at a 76 MHz repetition rate.
•semiconductor lasers at 473, 660 and 980 nm.
In most of our experiments these lasers are used in combination with a confocal microscope, high precision translation stages, monochromators, CCD detectors, avalanche photodiodes and several personal computers for data acquisition and analysis.
