Product Introduction

RTP, which has only recently become commercially available, is the material of choice for many NLO and electro-optic applications. Its high optical damage threshold makes it especially useful in high power SHG and OPO applications. RTP’s high electrical resistivity is important for many electro-optic applications, and in the production of Periodically Poled RTP elements.
