RESEARCH EXPERIENCE
-------------------
1987  --  present    Research Assistant.  Department of Physics, 
                     Texas A&M University

a.  Studied two photon resonance enhanced three photon ionization of atomic
    hydrogen.  A new high power laser system that produces laser pulses with a 
    Fourier transform limited linewidth was developed for this research.
    The laser wavelength was continuously tunable in the 243 nm region.  The
    results shed light on the apparent disagreement between recent 
    experimental data by other groups and the theoretical calculations.  The
    work is presently being extended to the direct detection of the metastable
    hydrogen atoms in order to obtain a rigorous determination of the two
    photon Rabi frequency.

b.  Worked on a project to measure the spectral absorption of water from 
    340-640 nm using photothermal spectroscopy.  Developed a scheme using
    near total internal reflection to significantly amplify the probe beam
    deflection angle and thus provide much higher sensitivity.  Made the
    first observation of the seventh harmonic of the O-H stretch in liquid
    water.  A Lambda Physik excimer laser (EMG 301 MSC) pumped dye laser 
    (FL 2002) system was used in this work.  The experiment was controlled
    by a computer with an IEEE-488 interface and LabView software.

c.  Participated in recent experimental work directed towards a demonstration
    of atomic phase coherence in sodium vapor.  A coherent 899 ring dye laser,
    an acoustic-optical frequency shifter and sodium cells are used in this
    work.

d.  Participated in construction of a colliding pulse mode-locked femtosecond
    dye laser.  Helped in development of an amplification system using a 
    novel integrating cavity dye amplifier that provides good beam quality.

e.  Built a laser intensity regulator based on a design that had been 
    previously developed in our laboratory.  The principle elements of the
    device are an electro-optic modulator, a linear polarizer, an operational
    amplifier, and a high voltage transistor amplifier.

1984  --  1986	Research Assistant.  Modern Physics Lab, Tongji University
 
    Studied the positron annihilation spectrum of silicon that had been
    irradiated by neutrons.  Measured the Mossbauer spectrum of concrete.

1984  Student Technician.  Department of Physics, Fudan University

    Worked on laser and electron beam annihilation of VLSI.

EXPERIENCE HIGHLIGHTS
---------------------

Laser systems

*   Designed and constructed an injection seeded Nd:YAG laser that produces
    1 Joule pulses.  The laser pulses have a smooth spatial profile with a
    Fourier transform limited linewidth (50 MHz).  The laser was originally
    a Molectron system whose oscillator head was changed to a self-filtering
    unstable resonator configuration.  The frequency locking technique that
    was developed is a novel new design which is based on a completely 
    different principle from commercial systems.  It can never run out of
    range and permits the laser to remain locked to a single longitudinal
    mode even in extremely high noise and vibration environments.

*   Designed and built a cw ring Nd:YAG laser that produces 500 mw in a signal
    longitudinal model.  Constructed a frequency stabilization system for it
    (both electrical and optical parts) which keeps the frequency jitter to 
    less than 5 MHz over a 24 hour period.

*   Modified a Spectra-Physics model 380B ring laser to the equivalent of
    a model 380D.  Built all the required electrical and optical parts.  The
    result is comparable with the commercial system (frequency jitter < 5 MHz,
    scanning range > 30 GHz).

*   Assembled a dye amplifier system.  Using KD*P doubling and RDP summing
    crystals, was able to obtain 5 millijoule pulses.  The latter had a 
    Fourier transform limited linewidth (single longitudinal mode) and were
    tunable in the 243 nm spectral region.

*   In conjunction with a post-doctoral fellow, built a colliding pulse
    mode-locked femtosecond laser in 1988.  The laser operated at 620 nm and
    the minimum pulse width we observed was 35 femtoseconds.

Ultra-high vacuum systems

*   Constructed an ultra-high vacuum system (10^-10 torr base pressure).  
    Designed and built an RF discharge source with appropriate differential
    pumping to produce an atomic hydrogen beam in the UHV environment.
    Designed and built a time-of-flight mass spectrometer for detection of
    hydrogen atoms.  A detection system for metastable hydrogen atoms was
    also constructed.        

Computer skills

*   Implemented a computer controlled data acquisition system.  Very familiar
    with the Macintosh computer and used LabView software to control the
    whole experiment.  Experienced in various other data acquisition 
    software such as ASYST, as well as to interfacing techniques between a
    computer and experimental apparatus.  Experienced in FORTRAN, BASIC and
    Assembly language programming.  Have also used both VAX systems and IBM
    computers to analyze data.

Electronics

*   Enjoy working on electronic circuits.  Designed and built the control
    systems for the ring lasers.  Generally fixed all electronics problems
    by myself, including everything from power supplies to laser control
    systems.  Familiar with many data acquisition techniques such as boxcar
    integrators, lock-in detectors, optical multichannel analyzers, photon
    counting techniques. etc.
