Part of the “How to Select” series, the “Guide to Custom High Power Laser Diodes” from Intense Ltd. is targeted to design engineers. The 10-page downloadable document includes guidelines for laser diode specifications, including a flow chart to help determine laser diode requirements and the supplier’s ability to meet them. An overview of design and prototype considerations includes discussions on packaging and active versus passive temperature control. Sections on finding the right diode manufacturer and on lasers enabled with quantum well intermixing technology are included. Laser applications and major semiconductor laser materials and wavelengths are listed.
