Abstract

A new design to lock frequency in directly doubling blue lasers is presented. We employ external gratin placed on the PZT tube to feedback lock the frequency of laser diode. The spacial distribution of LD is reduced 2.1 times and spectral distribution of LD is also compressed. Stability testing of blue laser is reported too.
