Figure C3.1.13. Experimental configuration for far-UV nanosecond CD measurements using a frequeney-upconverted Ti sapphire laser as a probe source. Pj and 2 are MgF2 Roehon polarizers at eross orientations. SPj is a strained transparent plate with about 1° of linear birefringence for quasi-null ellipsometric CD deteetion. Prism PMj and the iris select the far-UV fourth harmonie of the argon laser-pumped Ti-sapphire laser s near-IR fundamental output to probe the elliptieity of the sample. A seeond laser beam at 532 nm is used to pump CD...

The apparatus used in the studies which are the primary focus of our discussion is shown schematically in Figure 1. The details of the apparatus are discussed elsewhere (1.39). Briefly, the output of an argon ion pumped dye laser is brought into a suitably equipped vacuum chamber. Here, the laser beam intersects a supersonically expanded metal beam produced through use of an appropriate oven system. The oven depicted in the figure is a... 

We report on saturated absorption experiments in Na2> realized with a tunable and stabilized argon laser. These experiments provide both spectroscopic and physical results, which help in understanding the behavior of optically pumped alkali dimer lasers. We briefly describe a new double resonance experiment which enables us to study the gain line-shapes of the dimer laser and to demonstrate the backward-forward gain competition. 

Let us now turn to two-photon excitation via an intermediary level. In this chapter we restrict ourselves to processes without energy transfer, that is, typical one-ion processes. A recent and intensity-rich example is Eu " in LaOCl (41). Excitation of the Do level of Eu (cf. Fig. 6) does not only yield the usual emission transitions from the Dq level, but also yields anti-Stokes emission from the higher Di,2,3 levels. The intensities of these emissions were at least one order of magnitude smaller (for excitation with a continuous dye laser pumped with an argon ion laser).
