This web page contains Thorlabs' laser diodes with center wavelengths from 405 nm to 785 nm. Diodes are arranged by wavelength and then power. The tables below list basic specifications to help you narrow down your search quickly. The blue Info button next to each part number within the tables opens a pop-up window, which contains in-depth information regarding each diode.
We offer diodes in various packages including standard Ø5.6 mm and Ø9 mm TO packages, as well as Fiber-Pigtailed TO-Packaged Diodes. We have categorized the pin configuration of TO-packaged diodes in to standard A, B, C, D, E, and F pin codes (see image below). This pin code allows the user to easily determine compatible mounts. 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 each diode, this 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. Diodes can be temperature tuned, which will alter the lasing wavelength. A number of diodes are listed as Wavelength Tested, which means that each diode has been tested and the dominant wavelength has been recorded. Customers may contact Technical Support to select one of these diodes based on the tested wavelength.
Many applications require single mode lasers. Many lasers offered here will lase a single longitudinal mode and a few are designed for muliti mode operation. In addition, we offer several different types of laser diodes with different output characteristics (power, wavelength, beam size, shape, etc.). Please see our Laser Diode Tutorial for more information on these topics and laser diodes in general.
