  • Compatible with Thorlabs' Laser Diode Mounts and Controllers (See Table to the Right)

Superluminescent Diodes (SLDs) are excellent high-power, broadband light sources that are ideal for use in applications such as display technology, holography, metrology, and spectroscopy. When fit into an external cavity, these SLDs can be used as a tunable laser. This page contains Thorlabs' SLDs with center wavelengths from 405 nm to 650 nm that are built into a TO-56 package with pin code H. Visible SLDs in a butterfly package are also available, as well as NIR SLDs for wavelengths from 810 nm to 1550 nm, many of which are ideal for spectral-domain optical coherence tomography.

The SLDs featured on this page are single spatial mode and have a near-Gaussian optical spectrum. More detailed typical specifications for each item, as well as mechanical drawings, are available in the tables below.

With an H pin code, these visible SLDs are compatible with Thorlabs' S7060R diode socket and the LDM56 laser diode mount, which has an integrated thermoelectric cooler (TEC). These mounts are compatible with Thorlabs' laser diode and temperature controllers; see the table above for details. Please note that optical feedback can diminish the output power or damage the SLD and back-reflections should be avoided. SLDs are also sensitive to electrostatic shock, and proper precautions must be taken when handling the device (see our electrostatic shock accessories).

Dear tech support, I am using the SLD405T with the LDM56 mount. Above around 50 mA (few mW optical power output) the power fluctuates. I am suspecting a wrong orientation of the SLD into the mount and/or a wrong polarity switch setting. Can you tell me how to plug it properly ? The style H diagram and the indications in the MFGSpecSheet document are confusing to me. Thank you for your help.

Dear Thorlabs, I purchased the SLD450T and the optical beam does not look uniform at all. With the adjustable collimation tube (LTN330-A), it is impossible to find something close to a collimated beam. I use it for a microscope-like experiment and the image is speckleized. Is it normal ? Do you know what could be the reason ? Do you have solutions for these problems ? Thank you for your help. Best regards.

Dear Thorlabs We are looking for a laser diode mount to drive SLD650T. Because SLD650T has a wide diverging angle, it requires high NA. Currently, we are usingLDM9T/M but it has large averation due to the short focal length(3.1mm) compared to the margin of the thread mount. Therefore, we want to use LTN330-B but it does not contain the TEC. Could you recommend any other laser diode mount for SLD650T? Best regards.

Thank you very much for contacting us! Our recommended mount for these SLDs is LDM56. We will reach out to you directly to discuss your application in detail.

  • Values are typical unless otherwise noted.
  • Basic superluminescent diode characteristics can be measured by increasing current (I) while measuring the device voltage (V) and light output (L). The resulting data is usually referred to as an LIV curve.
  • For more information on how the center wavelength for our NIR SLDs is defined, please see the Specs tab on the NIR Superluminescent Diodes presentation.
