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.
This laser adopts semiconductor laser chip, and the professionally designed drive and temperature control circuit temperature control ensures the safe operation of the laser, stable output power and spectrum, and excellent spot quality (TEM00 mode).

Ytterbium-doped Fiber Amplifier PM Fiber Laser Source Benchtop
The following is a demonstration of the operation of the desktop YDFA button control. Let’s check it now.
This is a Ytterbium Doped Fiber Amplifier with PM Fiber. The working wavelength is 1030nm~1070nm. It supports ACC and APC working modes. We can switch the APC/ACC working mode with the left and right buttons. At the same time, this machine also supports power regulation. In the APC working mode, press the up and down arrow buttons to adjust the power.
Ytterbium-doped fiber amplifier (YDFA) generates gain by pumping ytterbium-doped fiber with a semiconductor laser, and is used to amplify laser signals in the 1030~1100nm band. PM980 polarization-maintaining fiber output, the output power is continuously adjustable, and has the advantages of high gain and low noise. The desktop YDFA is convenient for experimental operation, and the user can adjust the pump current and output power through the buttons on the front panel. A more compact modular YDFA is also available, which is convenient for users’ system integration. Both desktop YDFA and modular YDFA can support PC software control and serial port command control.
