Production of Testing of Laser Crystals

PDF Version Also Available for Download.

Description

Lasers and nonlinear optical system are being developed to allow the construction of all solid state lasers with tunable output in the mid-infrared (3-5{micro}m). In these systems potassium titanyl phosphate (KTP) and its analogs (KTA, RTA and CTA) are used to construct Optical Parametric Oscillators (OPOs). In the past, large (5 mm x 5 mm x 15 mm) crystals of KTA, RTA and CTA have been difficult to obtain, and were costly as well. Also, the arsenate materials were limited in spectral range due to an AsO{sub 4} overtone in the 3.5 to 5.0 {micro}m region. There has also been ... continued below

Also, the arsenate materials were limited in spectral range due to an AsO{sub 4} overtone in the 3.5 to 5.0 {micro}m region. There has also been interest in materials which self-OPO. This process is done by doping nonlinear materials with lasing ions. This effort investigated the development of mixed metal analogs of KTA, which would last and also suppress the AsO{sub 4} absorption overtones to allow more efficient mid-infrared OPO operation.
