Laser Emission of a Neodymium Salt Dissolved in POCl3

High Energy Pulsed Liquid Laser

“…or possible mul tiple species is obtained from the Nd 3 spectra (Figures 2 and :)). Here at least eight clearly defined components can lie found in the 4 F3 2-4 l9 2 (resonance) transition region in all three types of solution, indicating a complete splitting of both upper and lower states (ten possible energies) While this does not agree with a nearly octahedral sym melry inferred by Kato from the laser behavior 23 and Tb 3 -spectra, 24 it is completely consistent with various studies in the Soviet Union, 2 * and appears unequivocal. The effect of acidity on the Nd 3 • spectrum is shown in Figure 4 In all three cases, when the Lewis acid concen tration is below stoichiometrie there is no measurable dis tortion ot the spectrum from the normal (stoichiometrie) situation shown in Figures 1-4, indicating no significant emission from more than one species.…”

“…First, it improves the heat transfer rate at the cell wall and secondly, it extends the low gradient region in the laser liquid further towards the cell wall. These factors bring about the two effects seen in [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25]first,P max increases, o max increases and, secondly, the value of E/E at P…”

“…The first indication was the use by Schimitschek 24 of ZfCL, TiCl 4 and BBr 3 to enhance the fluorescence yield of Nd(ClO ) dissolved in POC1…”

“…If we assume that the diameter d of a "bead" can be identified with the Airy disc of a dif- In another experiment (see Figure 5- 24), the lens L was placed so that its focal point was 20 cm in front of the spectrograph pinhole. With wire stops placed at this focus, no light from the laser could be detected entering the spectrograph independent of the position of another lens placed between the stop and the pinhole.…”

“…For observation of Stokes shifted light a 3-67 Coming filter was used. The exposed film containing both spectral and angular [24], [25] information is shown in Fig. 7.…”
