Facilities

1. Diode lasers (Thorlabs diode and temperature controllers,  TED 200 and LDC 205) and superluminescent light diodes. These light sources are used for coherence domain imaging and multi-wave mixing in photorefractive materials including photorefractive multiple quantum wells and polymers.

2. Photometric Cascade II Cooled CCD camera (-80C CCD temperature, 512x512 pixel, 16bit, EMCCD). The CCD camera has been used for biomedical imaging (coherence domain and diffusion photons).

3. Continuum Powerlite 6050 Nd:YAG lasers (Wavelength-1064nm, 532nm, and 266nm. Pulse width-9ns, repetition rate-50Hz. Out put pulse energy~190mJ). The laser is the laser source for second harmonic generation, UV detection and photo-acoustic research. Data acquisition is based on a dual-channel boxcar system and a LabView interface. 

4. ATI Mattson Infinity Series FT-IR spectrometer and Galaxy Series 5000 FT-IR spectrometer with a microscope.

5. Micro-Raman system (SPEX 1877 0.6m Triple Spectrometer, Olympus BH2-UMA). The light source for Raman system is an Ar-ion laser (Omnichroma, wavelength-532nm. Output power-70mW).

6. Digital Instruments Nanoscope IIIa AFM/STM.
