The basic principles of flow cytometer are introduced on the basis of diode pump solid state laser (532 nm) as a excitation source and a high gain avalanche photodiode (APD) arrays as a light detector a verification opitical system is built. Then Spherotech Rainbow Calibration Particle RCP-30-5A is used to evaluate the performance of the opitical system the fluorescence PE signal histogram of RCP-30-5A microshphere shows that the number of individual peaks is close to eight which is close to the world advanced level. 2011 IEEE.

The Raman scattering of I2 liquid-core optical fiber under the condition of resonance absorption in liquid-core optical fiber is studied in this paper. Iodine is dissolved in transparent benzene to make solution of I2 in benzene and the absorption coefficients of the solution are measured at certain wavelengths. The absorption curve can be divided into non-resonance absorption region pre-resonance absorption region strict resonance absorption region and post-resonance absorption region respectively. Resonance absorption Raman scattering experiments are conducted by a 532 nm frequency-doubled Nd:YVO4 laser and the wavelength is in the strict resonance absorption region of solution of I2 in benzene. Compared with I2 the absorption of benzene can be neglected. Non-resonance Raman scattering of the solution is performed using a 632.8 nm He-Ne laser and no spectrum lines of I2 are found. The study demonstrates that there is one spectrum line of I2 in the Raman scattering spectrum in the I 2 liquid-core optical fiber but this line is not found in the spectrum of the non-resonance and resonance absorption Raman scattering of I2 solution in benzene using absorption cell. The experiments proved that I 2 Raman scattering is greatly enhanced by using both resonance absorption and liquid-core optical fiber.

The work on laser varicose treatment carried out in CIOMP It provides minimal invasion CAS cooperating with The First Clinical Hospital often under local anesthesia and intravenous sedation thereby eliminating the need for general anesthesia Jilin University is summarized. Dozens of animal experiments adopting dog and rabbit samples are made in a long time of several years. Different lasers are used greatly shortens postoperative recovery term including long pulse frequency-doubled Nd:YAG(532nm) and semiconductor laser(808nm). Dozens of animal experiments show that laser has good efficacy to occlude the vein vessels. It has precise adjustability and relatively short treatment time only needing outpatient office setting with high cost and effect rate and it is highly safe with no side effects and no serious complications.

Laser treatment represents an attractive option to other methods of vessel diseases especially varicose veins. A long pulse (30-50ms) 532nm laser (Fig.1) is used in our experiments with the pulse duration matching the thermal relaxation time of the vessels and the green laser matching the absorption spectrum peak of the blood. Laser irradiates nude vein vessels directly or exterior skin to finish operation faster and to acquire the practical data for upper enteron varicose vein treatment in several animal experiments performed in vivo. The 5J-energy pulse allows us to finely occlude rabbit or dog's vein vessels up to 2 mm in diameter when irradiating them off external skin (Fig.2). Blood vessels are occluded at once and later biopsy specimens show the immediate and long-term lasting occlusion effect. While irradiating vessels directly (Fig.3) the vessels are usually irradiated to perforate detailed causes are still under investigation. Animal experiments show long pulse green laser therapy is a safe and effective solution to the vein's occlusion which promises such laser with high energy of each pulse and 30-50 ms duration is an ideal candidate for vessel diseases treatment.
