Abstract:

Three types of liquid lasers are reported the organometallic chelates, organic dye lasers, and neodymium - selenium oxychloride. The europium and terbium chelates, historically the first liquid lasers, are characterized by extremely high absorption by the organic moiety in the pumping regions thereby preventing any significant penetration of pump flux into the laser solution. This inherent limitation dictated the use of small active volumes in narrow-bore 1 mm laser cells. The resulting high threshold, low output liquid lasers could not compete in performance with the more efficient solids. Author
