Wide Acceptance Angle of Second Harmonic Green Generation by Periodically Poled Potassium Niobate

Not Accessible

Abstract

A KTP is a most popular nonlinear crystal for generating green light because of its wide temperature acceptance. It is well known that a KTP shows optical damage (gray tracking), especially under at high power density. A potassium niobate (KN) is expected as an nonlinear crystal for the highpower green laser, since it does not show optical damage under high power density at room temperature. However, its critical phase matching suffers from narrow angle acceptance (Δθ̕ = 0.03 deg/cm), which deteriorates the transversal beam shape. We fabricated periodically poled potassium niobate (PPKN) for green generation and SHG characteristics were compared with the conventional angle-cut KN(θ̕ = 71,ϕ = 90, L = 5 mm).
