SM Fiber Laser System SLD Broadband Light Source

SLD broadband light source adopts super radiant semiconductor diode light-emitting chip, which outputs broadband spectrum with low coherence degree and high output optical power spectral density. The operating wavelength can be selected from O, S, C, L and other bands, suitable for optical OCT, optical fiber sensing applications.

This is a 1550nm 10mW SLD light source of module type. It is equipped with a single mode fiber. It can be customized power adjustable version. When the power adjustment is selected, the power adjustment is controlled through the RS232 serial communication. The standard version is a fixed power mode, the light source is controlled by the button. We tested it with an infrared photosensitive film, and we could see a light spot.

405nm SM Fiber Laser Controlled by Button Operational Demo

This is a video about a desktop laser with button control of the laser output. we demonstrate with a 405nm 20mW SM fiber laser. It is controlled by buttons by default, and it can also be controlled by software. The laser is equipped with single-mode fiber output, and polarization-maintaining fiber output can also be customized. It has LCD display, real-time display of current power. The power is adjustable, and the adjustment accuracy is 0.1mW. Let’s check it now.

Adjust the laser output power:
Press the middle square button to enter setup mode.
The left and right arrow buttons are used to select the digital position to be adjusted.
The up and down arrow buttons are used to adjust the size of the numbers.
Finally press the middle square button to save and exit the settings.
When the key is turned ON, the Active indicator lights up, indicating that there is laser output.

ASE Broadband Light Source with Two Fiber Outputs

This is a custom ASE broadband light source with built-in circulator. Unlike the standard ASE, this custom ASE has 2 fiber outputs. The two output fibers are the 2nd and 3rd fibers of the circulator. Let’s check it now.

The fiber ASE broadband light source is an incoherent light source, which is the spontaneous radiation generated by the semiconductor laser pumping erbium-doped silica fiber, and the spectral flattening technology is introduced to achieve a broadband flat spectrum. The wavelength of the light source covers the C-band, and the spectral flatness is better than 2dB. It is output through single-mode fiber or polarization-maintaining fiber, which is suitable for applications such as fiber sensing.
