The effects of C5H10, C6H14, C7H10 and C8H18 on the energy outputs of D2O and CH3F and their mixture D2O-CH3F pulsed optically pumped FIR lasers has been studied experimentally. It is shown that all of them can increase the energy outputs at 66μm, 114μm and 385μm lines from D2O and at 496μm line from CH3F. Especially the net increases at long wavelengths (385μm and 496μm) are up to 30~90% by adding these vapours. Authors account such effects for their intense scattering, so more pumping photons trapped...

本实验研究了环戊烷、乙烷、正庚烷和正辛烷等四种烷类蒸汽对脉冲光泵D_2O和CH_3F以及D_2O-CH_3F混合气体超辐射远红外激光器输出能量带来的影响.发现它们均能使D_2O发射的66μm、114μm和385μm以及CH_3F发射的496μm谱线能量有不同程度的增加.其中,对长波长谱线(385μm和496μm)输出能量的影响最为显著,净增加达30~90%.本文把这种作用归因于它们对泵浦光的强散射作用,从而使泵浦光被活性分子更多地俘获,以及相对于它们的分子量来说有大的振动热容量,从而减轻瓶颈效应.

It is found that there appear strong 450 and 360 nm and weak 347 nm fluorescences. Through careful experiment al investigation and theoritical analysis, we find that the 450 and 360 nm radiations are 1D2→3F4,3H6 two-photon upconversion fluorescence and 347 nm radiation is 1I6→3F4 three-photon fluorescence.

The up-conversion luminescence phenomenon of TmP5O14 crystal at room temperature pumped by pulsed DCM dye laser is studied. It is found that there appear strong 450 and 360 nm and weak 347 nm fluorescences. Through careful experiment al investigation and theoritical analysis, we find that the 450 and 360 nm radiations are 1D2→3F4,3H6 two-photon upconversion fluorescence and 347 nm radiation is 1I6→3F4 three-photon fluorescence. The up-conversion process can be elucidated as follows: when a Tm3+ ion absorbs a first pumping photon and reaches the 3F2 state from the 3H6 bound state, the population of 3F2 state falls down rapidly to the 3H4, state due to the rather strong nonradiative relaxation. Then the excited state absorption from 3H4 to 1D2 takes place and the 360 nm two-photon up-conversion fluorescence from 1D2 state is appears. Meanwhile, there is a small possibility for energy transfer between 1D2 state and 3H4 state. It results in a converted population with respect to the 1I6 state and the 347 nm three-photon up-conversion fluorescence is appear, the up-con-version mechanism of which is a complicated process involving both the excited state absorption and the temperature of photons.
