With their circularly symmetric geometry and beam emission perpendicular to the semiconductor wafer they're fabricated on, vertical-cavity surface-emitting lasers (VCSELs) have some unique advantages over their diode-laser brethren. These advantages extend to beam characteristics, cost, and unusual configurations not possible with ordinary diode lasers. This webcast will cover the technology and characteristics of VCSELs, what wavelengths and powers they can now achieve, and both their traditional applications and the new areas of use they're expanding into.

Princeton Optronics :

Located in Mercerville, NJ, Princeton Optronics is the leading manufacturer of low cost, high and low power VCSEL devices and arrays for applications such as (i) speckle free illumination and ranging with single chip CW and pulsed power of several watts to >100W, (ii) end and side pumping of solid state lasers with power from a single chip of >200W, (iii) single mode VCSELs from several mW to >1W with low noise and narrow linewidth for applications such as sensing, atomic clock, and certain high brightness applications (iv) single and multimode devices for certain high speed applications. Princeton Optronics VCSELs are high efficiency compared to the rest of the industry, with demonstrated efficiency >55% for single devices and arrays. They also work at high temperatures to 100 deg C.
