Laser krypton-ion

A large number of nonlasing plasma lines emitted from the discharge plasma tube often interfere in the recorded Raman spectra. Loader (40) listed tables of plasma lines when using the argon ion and argon/krypton ion lasers as Raman sources. 

The p.c.s. measurements were carried out using a Malvern multibit correlator and spectrometer together with a mode stabilized Coherent Krypton-ion laser. The resulting time correlation functions were analysed using a non-linear least squares procedure on a PDP11 computer. The latex dispersions were first diluted to approximately 0.02% solids after which polymer solution of the required concentration was added. 

Laser Raman spectra were obtained with the 647.1 nm line of a krypton ion laser (Lexel, Model 95). The radiation intensity at the sample was 300 mW. The scattered radiation was passed through a double monochromator...

The macromode spectra described here are acquired with an Instruments SA Jobin Yvon Ramanor HG.2S system. Sample excitation is done with either argon or krypton ion lasers. This scanning spectrometer has a thermoelectrically cooled PMT detector and is fitted with a modified Nachet 400 microscope accessory for Raman microprobe work. The microprobe is capable of providing information from domains as small as 1 // in diameter. 

Krypton ion laser A CW or pulsed laser emitting lines from 337 to 859 nm from singly ionized krypton. Principal emissions are at 530.9, 568.2, 647.1, and 752.5 nm. 

Use Mathcad or some other symbolic algebra program to solve the Ai secular determinant of Table 41-2 in a manner similar to that shown in Fig. 5 for the Bi determinant. Modify the Mathematica commands shown in Fig. 6 to see the square of the I2 harmonic oscillator and Morse wavefunctions and their overlap product for v" = 2 and v = 0, 5, 10, 15, 20, and 25. Obtain plots of these results and discuss the trends that you see. Repeat the exercise for v = 40 and v" = 0, 1, 2, 3, 4, and 5 and note the dramatic intensity variations for the Morse oscillator. Emission from this state, which can be populated by the 520.8-nm krypton ion laser line, is strong to even v" levels but is very weak to odd v" levels (up to about v" = 30).

Jobin-Yvon Ramanor HG-2S spectrometer with double monochromator. Red light of 647 nm from a krypton-ion laser (Spectra Physics Model 165) and 514.5. 488 and 457.9 nm radiation from an argon-ion laser (Coherent Radiation Co., Model CR-2) were used.

Dynamic light scattering measurements were performed with a Malvern photon correlation system eqxiipped with a krypton ion laser KR 165-11 from Spectra Physics (1 =647.1 nm). The intensity time correlation function (TCP) was recorded by a Malvern autocorrelator. The electric field TCP g,(t) normalized to the base line of the intensity TCP, and its first cumulant F = -Slng (t)/3t at time to were calculated as usual ( )by an on-line computer where 80 cheinnels of a total of 96 chemnels were used for the recording of the TCP, and the leist 12 channels, shifted by 164 seusple times, were used for the detection of the beise line.
