16 μ and 8.5 μ generated via stimulated Raman process in potassium vapor

16-μ and 8.5-μ tunable lasing outputs were obtained from two sequential stimulated Raman scattering processes in K vapor using two visible dye lasers concurrently. Greater than 10 mW of 16-μ output was obtained for a 1-kW pump power. Tuning range of 2–4 cm−1 was observed. Kinetic information on the quenching of the 4P levels of K was deduced from the 16-μ signal amplitudes as a function of the delay time between the two lasers.

Opto-acoustic spectroscopy with a visible CW dye laser

The first use of a tunable visible laser in conjunction with an opto-acoustic cell is described. By using a longitudinal resonance of the gas cell NO 2 can be detected around 10 p.p.b., the same order of detectivity as in the infrared. The use of the technique for studying photodissociation in the visible and u.v. is discussed.

Highly efficient frequency doubling of visible dye laser radiation in RDP

The highly efficient frequency doubling of the high-power visible dye laser radiation in rubidium dihydrogen phosphate (RDP) is reported. An over-all power conversion efficiency of 52% was obtained at a fundamental pump power of 7 MW at 6370 Å. In addition, the temperature variation of the birefringence of RDP has been measured to be d (ne2−n01)/dT= (1.1±0.1) ×10−5 °C−1.
