Princeton Optronics Inc. has released 40-W continuous-wave 808-nm (PCW-CA1-40-W0808) and 976-nm (PCW-CA1-40-W0976) backreflection-immune vertical-cavity surface-emitting lasers (VCSELs). The devices comprise a 2-D planar VCSEL array mounted on a high-thermal-conductivity submount with a copper base. They have a spectral width of ~0.8 nm, a thermally stable emission wavelength (0.06 nm/K) and low beam divergence with a numerical aperture of ~0.14. Not subject to catastrophic optical damage, they also can be operated in quasi-continuous-wave and short-pulsed (<20 ns) modes. They are suitable for use in solid-state laser pumping and medical applications.
