Separation of Li isotopes by laser deflection of atomic beams has been carried out. An atomic beam apparatus with a collimating ratio of 450/1 generates a Li atomic beam of 109 atoms/cm3 at the oven temperature of 600C.

Separation of Li isotopes by laser deflection of atomic beams has been carried out. An atomic beam apparatus with a collimating ratio of 450/1 generates a Li atomic beam of 109 atoms/cm3 at the oven temperature of 600C. The CW tunable dye laser crossing the atomic beam at a right angle has a linewidth of 6 MHz and its intensity at the 1 cm interaction area is about 70 mW/cm2. When the laser frequency is tuned to coincide with 7Li 22P3/2F=3-22S1/2 F = 2 transition, TLi atoms are deflected from the beam. The deflected atoms are very pure 7Li and almost does not contain 6Li. When the laser frequency coincides with any other transition of 22P -22/S of both 6Li and 7Li, no apparent deflection is observed because of the optical pumping of the hyperfine levels of the 22/S1/2 ground state..

Synchronously pumped optical parametric oscillators with pumping depletion
Liang Peihui
The generation and evolution of LiNbOa optical parametric oscillators synchronously pumped by frequency-doubled light from a mode-locked Nd:YAG laser has been studied by computer numerical simulation.

The generation and evolution of LiNbOa optical parametric oscillators synchronously pumped by frequency-doubled light from a mode-locked Nd:YAG laser has been studied by computer numerical simulation. It is shown that under the condition of pumping depletion the shapes and durations of the pulses in a signal wave pulse train are distinct from each other. The pulse duration in front of the train is shorter than that in the middle and at the end of the train(from 7 ps to about 20ps),meanwhile most of the pulses have substructures. Cavity length dismatch does not broaden the pulse very much but mainly reduces the output energy. The shape, the duration of pulses and the dismatch length of cavity are affected by the gain of the device..

If oscillation of laser light is considered as the linear harmonic oscillator of photons oscillating in a resonator the uncertainty relation of laser light with higher order modes can be obtained, and it is in agreement with the previous experimental results..
