Linear and nonlinear optical properties of 2-cyclooctylamino-5-nitropyridine (coanp)
Abstract
The optical and nonlinear optical properties of 2-cyclooctylamino-5-nitropyridine (COANP) have been investigated. The refractive indices exhibit strong dispersion and a high birefringence (0.15 - 0.3) in the visible. The three main refractive indices at Λ = 550nm are na = 1.670, nb= 1.875 and nc= 1.683. Calculations carried out show interesting critical (frequency-doubling of Λ = 1064 nm (Nd laser)) and noncritical phase-matching properties. The nonlinear optical susceptibilities d32 = (32±16) pm/V and d33 = (13.7±2) pm/V were measured. © 1989 SPIE.
