Googlaser is my new toy. It is a customized search engine on lasers, using Google Co-op. The advantage of Googlaser is that it only searches in selected websites, so the relevence of the search results is improved. The results can be refined further by labels. I will only include most relevent websites in the search engine.
We obtained 1.1 W 589nm orange laser yesterday by an approach of fiber Raman amplifier and external frequency doubling. It is only a brief test, so we are rather confidence to scale the power to over 2W in next tryments. The laser is linear polarized and the linewidth is below 2GHz, which is good for laser guide star application. Compared to what I had done one and half years ago, it is a big improvement.
1 W level compact orange laser has big market already. We are thinking of the potential to scale up to >10W. The only obstacle seems to be the nonlinear crystal.
19/08/05 update: I was too optimistic. We could get up to 1.6W only. Many problem with the crystals.
23/08/05 update: We get 2.9W now, with efficiency ~23%.
