Materials with Nonlinear Optical Properties
Facilities and List of Equipment
A number of facilities in the Chemistry and Physics Departments are available for our research effort in inorganic materials these include:
- Multinuclear NMR facility- 300MHz multinuclear NMR spectrometer (Bruker);
- 400 MHz multinuclear NMR spectrometer(Bruker);
- X-ray Crystallography Facility equipped with an Enraf-Nonius CAD4 single crystal X-ray diffractometer;
- A PC with SHELXTL-PC software for crystal structure solutions; and
- Microscopes for selecting and mounting crystals.
This facility allows the solid-state structures of materials that crystallize in single crystals to be determined. Catalysis Evaluation Facility is equipped with a computer controlled, 500 ml Parr High Pressure reactor This facility allows the effects of reaction temperature, pressure and the pressures of gaseous reactants on the rates of catalytic reactions to be evaluated.
Nonlinear Optics Laboratory is housed in the UAB Department of Physics. UAB's Nonlinear Optics and Laser Laboratory houses state-of-the art spectroscopic analysis systems including an Acton Research Corporation spectrometer system, a Shimadzu spectrophotometer system, and an imaging polychromator - lens-coupled intensified CCD camera combination. Auxiliary equipment includes a 80 ps resolution Tektronics digitizer, a Stanford Research boxcar integrator, a Janis crystrostat, a Spiricon beam profiling system, and a wide variety of optical components and mounts. In addition to a low power Nd:YAG laser, the laboratory also houses a Spectra-Physics GCR-250 high power Nd:YAG laser with injection seeder for single longitudinal mode. A Light Age alexandrite laser can be tuned in wavelength from 720 nm to 800 nm, extended to 300-1500 nm with our Raman cell module and frequency doublers and triplers. The temporal pulse width of the laser can be varied from 100 ps to 200 ms. More recently, a picosecond mode-locked Nd:YAG laser has been purchased to provide an additional ps pulsed laser source for optical measurements. This facility allows the linear and nonlinear optical properties of both solutions and thin films to be fully characterized.
