High Peak Power 808 nm Vertical-cavity Surface-emitting Laser Array
摘要
Abstract
In order to achieve high output power of 808 nm vertical cavity surface emitting laser (VCSEL) array, the DBR material of 808 nm VCSEL was optimized, and Al content of Alx Ga1 - x As was analyzed for the influence on refractive index and absorption. Based on the above analysis, 2 × 2 VCSEL array was designed and fabricated with non-closed ring structure. The peak power of the VCSEL array was tested under waveform analysis method. The peak power is 30 W in 60 ns pulse width and 100 Hz repetition rate, and 9 W in 20 ns pulse width and 100 Hz repetition rate, respec-tively. The near-field and far-field of VCSEL array were also measured. The beam divergences with full-width at half maximum are 16. 9° and 17. 6° in the vertical and lateral directions, respectively.关键词
