High Power Pulsed Intra-Cavity Frequency Doubled Vertical Extended Cavity Blue Laser Arrays

چکیده
Electrically pumped vertical cavity surface emitting lasers (VCSELs) can produce hundreds of mW's of 976 nm CW output in a TEM00 mode when operated with an external cavity configuration. During pulsed operation (<50ns) a significant increase in the peak power is observed, compared to CW operation. High peak powers makes these lasers very well suited for intra-cavity frequency doubling with a non-linear crystal. We are developing surface emitting lasers in 2D array format and high power pulsed blue laser arrays in a small size. We present results of CW and pulsed operation of such lasers.

The ability to fabricate monolithic two-dimensional (2D) diode laser arrays is a key step towards making high-power lasers at low cost, because the manufacture of such laser arrays eliminates labour-intensive fabrication and packaging [ 11. The surface-normal topology of the vertical cavity surface-emitting laser (VCSEL) makes it ideally suited to the formation of 2D arrays for high power appli...
