In this paper, the experiment of optoacoustic detection of stark spectroscopy for CH3C1 and CH3F molecules is described. This method has been compared with conventional optoeleotric detection. An optoacoustic signal is produced when a laser line coincides with a molecular absorption line which has been shifted by making use of stark effect, and is detected by a special microphone. The dependence of optoacoustic signals on sample gas pressure has been determined and derivative signals of a number of line...

In this paper, the experiment of optoacoustic detection of stark spectroscopy for CH3C1 and CH3F molecules is described. This method has been compared with conventional optoeleotric detection. An optoacoustic signal is produced when a laser line coincides with a molecular absorption line which has been shifted by making use of stark effect, and is detected by a special microphone. The dependence of optoacoustic signals on sample gas pressure has been determined and derivative signals of a number of line components of CH3F molecule under the condition of 11500V cm stark field and 150 mTorr pressure have been recorded. The experiment indicates that the optoacoustic signal decreases rapidly when the pressure is reduced in order to apply high stark field to the sample gas,and it limits to obtain higher stark field. Authors have discovered that under similar conditions the optoeleotric detection has higher sensitivity and higher signal-noise ratio than optoacoustic detection. And yet the optoacoustic detection method may be improved undoubtedly by putting the laser closer to the microphone using higher laser power till the absorption saturated, and reducing the gap between two stark electrodes.

On the basis of ref. [1], the time-resolved absorption spectrum of vibrational excited states v3 in BCl3 molecules are observed and investigated in higher laser energy flux. The excitation of vibrational states and a variety of energy transfer processes in relaxation, as well as their dependence on the pumping laser energy, the pressure of BCl3 and other parameters are measured. The result shows that there exists an ensemble of nonthermal distribution in vibrational states and the rotational energy transfer plays an important role in generating this nonthermal distribution. The processes of development of the BCl3 vi-bratioal excited absorption spectrum are discussed by using a simplified dynamical collision model. A simple relation Prv-v = c/K'(Tv,T<0,q) for the redistribution of the vibrational states and the analytical expressions for the equivalent vibrational temperature and the average number of the absorbed photons are obtained. They are qualitatively in agreement with experimental results.

The effects of nitrogen laser irradiation and psoralen phototoxicity on the growth of C.albicans were examined in vitro.Nitrogen laser irradiation at low energy (Iess than 0.6mJ/sq cm) for 30' to 90' did not eauss any significant effect on the growth of C.albicans.Such irradiation in the presence of 8-MOP resulted in a moderate inhibitory effect on fungal growth.8-MOP application alone did not show such an ettect.Thus the ettect on fungal cells was a photoseusitization.At higher laser density(1.0...

The effects of nitrogen laser irradiation and psoralen phototoxicity on the growth of C.albicans were examined in vitro.Nitrogen laser irradiation at low energy (Iess than 0.6mJ/sq cm) for 30' to 90' did not eauss any significant effect on the growth of C.albicans.Such irradiation in the presence of 8-MOP resulted in a moderate inhibitory effect on fungal growth.8-MOP application alone did not show such an ettect.Thus the ettect on fungal cells was a photoseusitization.At higher laser density(1.0 mJ/sq cm),exposure of fungal suspensions in the presence or absence of 8-MOP for 15' to 90' resulted in a marked inhibitory or lethal effect on the fungus as measured by Ioss of colony forming ability.It seems that at certain laser densities,nitrogen laser irradiation alone is sufficient to inhibit fungal growth completely.These observations suggest possible clinical application of nitrogen laser in modern phototherapy and photochemotherapy.

实验研究了盘激光照射及激光加光敏剂8—MOP对白色念珠菌生长的影响。低能量氮激光照射(小于0.6mJ/cm~2)30′—60′未见明显影响。如外加8—MOP时对霉菌生长发生中等抑制作用,但单独应用8—MOP则未见抑制作用。因此,这种抑制是由于光敏化作用引起的。较高能量氮激光照射(1.0mJ/cm~2)15′—90′时,不论单独照射或外加8—MOP,皆使霉菌生长完全抑制。作者认为,达到一定能量的氮激光照射可完全抑制白色念珠菌生长,氮激光似可临床应用于光照疗法及光化学疗法。
