This chapter presents a short description of the physics of cw OPOs. After a brief presentation of the basic principles of OPOs, we will describe the properties of cw OPOs. The reader wishing to read further can read the references Byer, 1975 Brunner and Paul, 1977 Shen, 1984 JOSA, 1993 JEOS, 1997 CRAS, 2000. 

The effect of mode competition, which is generally the dominant effect, is more subtle since, to a first approximation, a cw dye laser has only one mode. Theories of IDLS which account for mode competition have been put forward by Hansch, Schlawlow, and Toschek (HST) and by Brunner and Paul (BP). HST start with a realistic set of laser rate equations but use substantial approximations to solve them. BP use an approximate and very empirical set of rate equations which they solve analytically. Each theory yields a prediction for the dependence of enhance-m it on pumping power P relative to the threshold pumping power... 

Up to 1910 all these roses were sold at O 10 fr. or 0 20 fr. per kilo from that time onwards, the red variety, Brunner, admitted to be the best, increased in value, and tetched 30, 40, and even 60 c. per kilo. The pink varieties, especially Van Houtte and Paul Nabonnand, the yellow varieties, Safranos, and the white varieties, Druski, remained at lower figures. These flowers are obtainable in millions of kilos, and it is estimated that 5000 to 10,000 kilos of roses are required to produce one kilo of essence. French otto has a clear and penetrating pe ume, similar to that of the freshly-cut flower.
