This web page contains Thorlabs' laser diodes with center wavelengths from 705 nm to 2000 nm. Diodes are arranged by wavelength and then power. The tables below list basic specifications to help you narrow down your search quickly. Lasers that are highlighted in light green in these tables below are single-frequency laser diodes. The blue button in the Info column within the tables opens a pop-up window that contains more detailed specifications for each item, as well as mechanical drawings.

Notes on Center Wavelength
While the center wavelength is listed for each laser diode, this is only a typical number. The center wavelength of a particular unit varies from production run to production run, so 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 items below are listed as Wavelength Tested, which means that the dominant wavelength of each unit has been measured and recorded. After clicking "Choose Item" below, a list will appear that contains the dominant wavelength, output power, and operating current of each in-stock unit. Clicking on the red Docs Icon next to the serial number provides access to a PDF with serial-number-specific L-I-V and spectral characteristics.

Packages and Mounts
We offer laser diodes in various packages including standard Ø5.6 mm and Ø9 mm TO packages, as well as Fiber-Pigtailed TO-Packaged Diodes, Chip on Submounts, and C-Mounts. We have categorized the pin configuration of TO-packaged diodes in to standard A, B, C, D, E, F, G and H 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. Chip on Submount and C-Mount lasers are better suited for OEM applications.

Spatial Mode and Linewidth
Most lasers offered here are single-transverse mode ("single mode") and a few are designed for higher-power multi-transverse mode ("multimode") operation. We offer laser diodes with different output characteristics (power, wavelength, beam size, shape, etc.). Some single mode laser diodes can be operated with limited single-longitudinal mode characteristics. For better side-mode-suppression ratio (SMSR) performance, other device such DFB lasers or external cavity lasers should be considered. Thorlabs also offers very narrow linewidth (2 W, are also available. Please see our Laser Diode Tutorial for more information on these topics and laser diodes in general.

Laser diodes are sensitive to electrostatic shock. Please take the proper precautions when handling the device; see electrostatic shock accessories. Lasers diodes are also sensitive to optical feedback, which can cause significant fluctuations in the output power of the laser diode depending on the application. For all of the pigtailed laser diodes, the laser must be off when connecting or disconnecting the device from other fibers, particularly for lasers with power levels above 10 mW.

IMPORTANT NOTES AND WARRANTY INFORMATION ON LASER DIODES
These laser diodes are designated for use solely as components and are not sold as a complete laser product.  The purchaser assumes the responsibility to comply with US 21 CFR 1040.10, US 21 CFR 1040.11, and IEC 60825-1, Edition 1.2 with regard to the use of these diodes and their introduction into commerce. 
Laser Diode Warranty

When operated within their specifications, laser diodes have extremely long lifetimes. However, most failures occur from mishandling or operating the lasers beyond their maximum ratings. Laser Diodes are highly static sensitive devices. Since Thorlabs does not receive any warranty credit from our laser manufacturers we cannot guarantee the lasers after their sealed package has been opened. Thorlabs will be happy to extend a full refund or credit for any lasers returned in their original sealed package within 30 days of purchase.

Please refer to the LD Operation tab for details on our warranty policies.
