2010 CLEO/Laser Focus World Innovation Award, Honorable Mention

The 2010 CLEO/Laser Focus World Innovation Award went to NTT Advanced Technology Corporation. TOPTICA received a honorable mention.

TOPTICA Photonics AG – Booth 1321

High-Power Tunable Laser Source for Sodium Spectroscopy and Other Applications

For the creation of a tunable, narrow-linewidth, high-power (30 W), 589 nm yellow laser for guide star, spectroscopy, LIDAR, phototherapy, and other visible and near-IR applications.

What is CLEO/Laser Focus World Innovation Award?

Each year, the CLEO/Laser Focus World Innovation Awards Program honors the most timely, ground-breaking products in the field of laser science. Designed to showcase some of the most significant new products in the field, Innovation Award entries are evaluated on criteria critical to product success: impact, functionality, life expectancy, effect on the optics industry, innovation and patents or trademarks.

I am pleased and proud because I contributed significantly to the development of the technology behind this product.

3 W orange laser based on fiber Raman laser

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%.
