Thorlabs ML520G71 Laser Diode has a center wavelength of 638 nm. It also has a Ø5.6 mm package. We have categorized the pin configuration of TO-packaged diodes in to standard A, B, C, D, E, F, G and H pin codes. This pin code allows the user to easily determine compatible mounts. For more information about the pin codes, please use the breadcrumb links at the top of the page and go to the Visible Laser Diodes: Center Wavelengths from 404 nm to 785 nm page. TO-packed diodes are the most widely supported diodes by our product line, followed by butterfly packaged lasers.

While the center wavelength is listed for this diode, it is only a typical number. The center wavelength of a particular diode varies from production run to production run, thus the diode you receive may not operate at the typical center wavelength. This diode can be temperature tuned, which will alter the lasing wavelength.

Laser diodes are sensitive to electrostatic shock. Please take the proper precautions when handling the device. Fabry-Perot lasers are also sensitive to optical feedback, which can cause significant fluctuations in the output power of the laser diode depending on the application. Members of our technical support staff are available to help you select a laser diode and to discuss possible operation issues.
