In the article,thawy red blood cells were studied by the means of Raman spectroscopy using Laser tweezers Raman spectroscopy system.

The concept of femtosecond laser tweezers was proposed.

Laser tweezers Raman spectroscopy(LTRS)system is a combination of Raman spectroscopy and laser tweezers;it is a new method to study cells;it can trap single living cell and make Raman spectrum of single living cell.

On the basis of constructing laser microbeam system we manipulate hollow dielectric spheres in suspension with optical trap,it validates the kinetic performance of the laser trap.

The computation of the optical trapping force is achieved by using a FDTD (Finite-Difference-Time-Domain) method.

One of the three models, the EM model, are the exact method for the simulation of the single fiber optical tweezers and for the numerically calculation of the optical trapping force.

Optical micro-manipulation is a new type of technology for micro-control, micro-fabrication and micro-measurement, which combines the capabilities of optical tweezers, femtosecond laser scissors and micro-spectrometer.

Single fiber optical tweezers which is a new kind of fiber optical tweezers are systematically analyzed in this dissertation.

In this paper, two types of laser methods for measuring parameters of hydro- mechanics were introduced: the fiber optical tweezers (a branch of optical tweezers) and the laser Doppler technology.
