Wavelength stabilization improves laser diode efficiency and brightness.

The article discusses the capability of wavelength stabilization technology for high-power laser diodes to bring an efficient spectral width that is locked over a wide temperature range. It notes that laser diodes are by a wide margin unsurpassed as efficient sources of radiation and have carved out dominant positions in many laser applications. The author points out that laser applications such as fiber-optic telecommunications and optical data storage would not exist at all without the diode.
