Ultrafast Optics & Optoelectronics Research & Teaching Facility
Equipped with state of the art laser systems, opto-electronic equipment and other basic optical and electro-optical components to investigate ultrafast photophysics and nonlinear optical properties.
Systems under study are bulk nanostructured and quantum well semiconductor structures, ultrashort pulses propagation in fibers and waveguides and high-speed lightwave systems.
  Femtosecond laser systems :
  Coherent femtosecond laser system: consists of a Ti:Sapphire oscillator, regenerative  
amplifier and an optical parametric amplifier (OPA)


Repetition rate capability from single-shot to 300 kHz.
Typical pulsewidth ~ 120 femtosecond pulses across a continuous spectrum with wavelengths from 350 nm to 2.5 mm.

Picosecond laser systems:

Two Time-Bandwidth SESAMs (semiconductor saturable absorber mirrors) passively modelocked Nd:Vanadate lasers at 1064 nm (8W) and 1342 nm (4 W), extendable by frequency doubling to 532 and 671 nm respectively. Both lasers operate at a high repetition rate of 76 MHz and short pulse duration ofI 10 ps.
Spectra-Physics Ti:Sapphire laser - tunable from 750-900 nm, capable of operating at either 1.5 ps or 30 ps.
In the teaching lab: High-Q SESAM laser operating at 10ps, 1064 nm (4W) with a repetition rate of 76 MHz.

Trivista triple Raman spectrometer:

Contains a total of nine standard gratings utilizing three turrets that are capable of operating from 250 nm to 2000 nm in a continuous manner. The system comes with a CCD camera, an InGaAs linear array and an InGaAs detector all liquid nitrogen cooled. 
The typical spectral resolution of the TriVista with the Spec-10 CCD camera is < 0.02 nm, all over the range, or 0.2 cm-1 (referred to 500 nm).  Extreme stray light rejection allows Raman spectra well below 10 cm-1 apart from the Raleigh line of the laser.
