In recent years there has been renewed interest in the scientific and indu­ strial communities in tunable solid state vibronic lasers. Much of this has been spurred by the user desirous of obtaining compact primary laser sources (independent of nonlinear optical frequency shifts) throughout the visible and near infra-red spectral regi ons. To further motivate and stimul ate re­ search and development in this area, workshops sponsored by the Laser Divi­ sion of the US ArmY Night Vision Electro-Optics Laboratory (NVEOL) at Fort Belvoir, Virginia were held during 1-3 April 1981 and 16-17 June 1983 at Keystone and NVEOL, respectively. The consensus of opinion of the partici­ pants at these workshops was that any successful program leading to the iden­ tification and development of vibronic tunable laser materials in the visible and IR must include coordinated activity between crystal growers, theoreti­ cal and experimental investigators into the fundamental processes of vibro­ nic lasing, and laser device engineers. Continued interaction between govern­ ment, industry, and academia was encouraged in order to establish a unified approach to these areas and, when necessary, redefine and redirect program­ matic activity. The organization of this 1st Annual Conference on Tunable Solid State La­ sers held at the La Jolla Institute 13-15 June 1984, was based around the latest results in tunable vibronic materials and laser development, but structured ina manner consi stent wi th the recommendati ons of the NVEOL workshops.
