Holographic Volume Bragg Gratings Stabilize Laser Diode Performance
Nov 1, 2003 — High-power multimode laser diodes, emitting >1 W per diode, and laser diode arrays, emitting tens or even hundreds of watts, have many important applications, such as medicine, materials processing and pumping solid-state lasers. The market for them in areas other than telecommunications is strong and growing.
These devices typically emit approximately 1 W from a 100 × 1-μm area, although some can emit as much as 4 W from an aperture of this size. The spectral characteristics of...
