Abstract

A blazed holographic optical element (HOE) has developed with injection molding technique. It is able to function as a beam splitter and aberration generator for focusing error detection of optical pick up head for optical storage system. The die was made by 4 axis controlled ultra precision cutting machine using single crystalline diamond cutting tool We carried out fabrication error estimation caused by cutting and injection, and derived adequate tolerance budget. The efficiency of HOE defined y the product of 0th and 1st order diffraction efficiency was measured by knife-edge method. We attained high efficiency of 15.5 percent which is close to theoretical limit. The efficiency is about 1.5 times as that of conventional non- blazed HOE.
