 This is 1615nm infrared fiber coupled laser source . The Optical fiber is removable. Its optical fiber interface is FC/PC, and it can be customized. The 1615nm  laser is an infrared laser, which cannot be observed by the human eye. We use an infrared sensitive film to observe the light spot. The output power is 0~200mW adjustable by adjusting the working current. To adjust the working current, turn the 'Adjustor' knob clockwise, when the current exceeds the minimum working current, the Laser indicator light turns green, and there is laser output at this time. When the 'Adjustor' is rotated clockwise to the end, it is the max working current and the max output power of the laser.

Today we are talking about software-controlled laser source . It is 450nm Blue fiber coupled laser source controlled by software. EasyHost is the control software. The connection between the laser and PC software adopts the communication protocol of RS232. The laser supports two working modes: CW/Modulation. When switching to Modulation, an external signal input is required. This is a fiber-coupled laser, and a free-space output laser can also be customized. Let's check it now. Software operation: Click the [Open COM] button to connect the control circuit of the laser. Multiple laser working parameters can be viewed/set in the software. As a special reminder, it is necessary to set amaximum working current parameter according to the current laser, so as to avoid the later adjusted current being too high and damaging the laser.

 This is a C-Band 30dBm module type EDFA . It is equipped with SMF-28e single-mode fiber, and polarization-maintaining fiber can also be customized. This is a high-power EDFA, with a row of aluminum sheets on one side of the shell for easy heat dissipation. This is a modular design, and desktop EDFA can also be customized. High power erbium doped fiber amplifier (EYDFA-HP-BA)，based on amplification technology of double clad erbium doped fiber ， unique optical packaging technology,  and with reliable hardware light path protection design, realized high power laser output in C band or L band， It has the advantages of high gain and low noise, and can be widely used in CATV, optical fiber communication, laser radar, etc.. The test report & spectrum analysis chart &  relationship between power current and output power of C-Band 30dBm SM EDFA.
