1550nm 37dBm 5W High Power SM Fiber Coupled Laser
What our laboratory demonstrates today is a 1550nm 37dBm IR laser coupled singlemode optical fiber output. The output power is adjustable with an adjustment range of 0.5~5W. The adjustment accuracy is 1mW. The Line-width here is 3.7 MHz, and the line width of 1MHz can be customized. The laser can be controlled through the buttons on the panel to adjust the laser output power. 1550nm is infrared invisible light, and the light spot can be observed with an infrared sensor plate. Let’s check it now.
This laser adopts DFB type laser chip, and cooperates with high-power gain optical path module to realize single-mode fiber output of single-wavelength high-power laser. The professionally designed drive and temperature control circuit control ensures the safe and stable operation of the laser, and the spectrum and power remain stable for a long time. The modular package has a compact structure, which is convenient for user system integration and is more suitable for engineering applications.
What is configured here is single-mode fiber, and polarization-maintaining fiber can be customized. The laser can also be controlled through software, and the communication interface is RS232. The following is the interface for the control software.
The power switch is on the back of the laser.The LCD panel displays the laser output power. Turn the key to ON, the laser is activated, and the Active indicator lights up.
Use the left and right buttons to select the number position to be adjusted (units, tens, hundreds, thousands). The up and down buttons adjust the value. The middle button is the confirmation key.
These are laser test reports, including the main parameters of the laser, spectrum diagram, power stability test, and line width test results.
