Abstract

beam-scanning makes these breakthrough lasers so much more awesome! I hope to never purchase a CO2 laser: bring on the 100W PCSELs!

Photonic-crystal surface-emitting lasers (PCSELs), which we invented in 1999, are currently attracting much attention for their simultaneous achievement of high output power and high beam quality (=high brightness) as well as their exhibition of functionalities that are not easily achievable with other types of lasers, such as polarization and beam-pattern control as well as on-chip beam-direction control, which eliminates the need for bulky external optics.

I'm still waiting for my 50W PCSEL galvo laser to cut clear acrylic
