Abstract : Experimental results of a direct measurement of the frequency shift of the output of a single-mode traveling wave ruby laser are reported. A description is included of the preliminary experimental results obtained in a successful attempt at eliminating this frequency shift by introducing a compensating phase shift in the optical cavity with the help of a nitrobenzene Kerr cell. Results of a detailed theoretical study and some preliminary experimental results on the phase locking of modes in solid state lasers are given. These results show the existence of and the reasons for such phase-locking effect. Results are reported of an attempt at obtaining single-mode operation of the YAG:Nd(3+) laser using the scheme suggested by Prokhorov, Burch, and Siegman. The results suggest that it is possible to achieve a single-mode operation with this scheme. Detailed results are given of a theoretical study on the shape of the resonant modes of the Fabry-Perot cavity of an oscillating solid state laser when the nonlinear spatial saturation effect is taken into account. Finally, a report is given of the results of a detailed study on the propagation of an intense light pulse through an optical medium.
