Spectroscopic measurements and laser performance of Ti:Al2O3 are discussed in detail. Data on absorption and fluorescence spectra and fluorescence lifetime as a function of temperature are presented. Laser characteristics observed with pulsed-dye-laser, frequency-doubled Nd:YAG-laser, and argon-ion-laser pumping are covered and show that nearly quantum-limited conversion of pump radiation can be achieved, along with tuning over the wavelength range 660–986 nm.

  1. Operation of the Ti:Al2O3laser was first reported by the author at the Twelfth International Quantum Electronics Conference in Munich in June 1982. Brief articles appeared in Physics News in 1982,” P. F. Schewe, ed. (American Institute of Physics, New York, 1983) and in Solid State Research Report (Lincoln Laboratory, MIT, 1982:3), pp. 15–21. A more complete description of the author’s efforts was in the chapter “Recent advances in transition-metal-doped lasers,” in Tunable Solid State Lasers, Springer Series in Optical Sciences, P. Hammerling, A. Budgor, A. Pinto, eds. (Springer-Verlag, Berlin, 1985), pp. 4–10. Work by others includes P. Lacovara, L. Esterowitz, R.
