摘要：

We report as much as 6-mu W upconverted cw radiation at lambda = 778 nm from the sum-frequency mixing of a 50-mW diode laser at lambda = 842 nm and a 200-mW CO2 laser at lambda = 10.2 mu m by use of a 15-mm-long silver This nonlinear material provides a convenient connection between IR and visible/near-IR We describe simple frequency chains based on this upconversion process that permit the absolute frequency measurement of many visible or near-IR possible standards at the 10(-12) accuracy level. Transposition of terahertz-scale frequency-difference measurements from the near IR to the 10-mu m domain is also proposed. (C) 1996 Optical Society of America
