Book excerpt: Method and apparatus for producing laser radiation by two-photon optical pumping of an atomic or molecular gaseous medium and subsequent lasing action. A population inversion is created as a result of two-photon absorption of the gaseous species. Stark tuning is utilized, if necessary, in order to tune the two-photon transition into exact resonance. In particular, gaseous ammonia (NH.sub. 3) or methyl fluoride (CH.sub. 3 F) is optically pumped by a pair of CO.sub. 2 lasers to create a population inversion resulting from simultaneous two-photon excitation of a high-lying vibrational state, and laser radiation is produced by stimulated emission of coherent radiation from the inverted level.

Available in PDF, EPUB and Kindle. Book excerpt: The motivating idea of the first Topical Meeting on Picosecond Phenomena, which took place at Hilton Head Island in 1978, was to bring together scien tists and engineers in a congenial setting who were developing picosecond lasers with those who were applying them to problems in chemistry, physics, electronics, and biology. The field has advanced remarkably in the following six years. This is reflected in the size of the conference which has more than doubled in the past six years and now includes scientists from many countries around the world. As evidenced by the papers in this volume, the appl ication of ultrafast 1 ight pulses continues to grow in new and diverse directions encompassing an increasingly wide range of subject areas. This progress has gone hand-in-hand with the development of new and more precise methods of generating and measuring ultrafast light pulses, which now extend well into the femtosecond time domain. It was this latter advance which was responsible for changing the name of the conference to Ultrafast Phenomena. The 1984 meeting was held at the Monterey Conference Center in Monterey, Cal ifornia from June 11 to 15 under the sponsorship of the Optical Society of America. A total of 320 registered participants, including 65 students, attended the three and one-half day conference. The overall enthusiasm of the participants, the high quality of the research presented, and ambiance of the setting combined to produce a successful and enjoyable conference.

This book was released on 1986 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Apparatus and method for generating continuous wave 16 .mu.m laser radiation using gaseous CF.sub. 4. Laser radiation at 16 .mu.m has been observed in a cooled static cell containing low pressure CF.sub. 4 optically pumped by an approximately 3 W output power cw CO.sub. 2 laser. The laser cavity employed was a multiple-pass off-axis-path two spherical mirror ring resonator. Unidirectional CF.sub. 4 laser output power at 615 cm.sup.-1 exceeded 2 mW. Computer calculations indicate that for modest pump powers of about 40 W, approximately 1 W of emitted laser radiation at 16 .mu.m might be obtained.
