 The 532nm 5mW DPSS (Diode Pumped Solid State) laser module is a laser that uses semiconductor pumping technology and solid laser gain medium, and is specially designed to produce stable and reliable 532nm green laser output. The 532nm DPSS laser module adopts a design that combines advanced semiconductor pumping technology and solid laser gain medium. The core is to use laser diodes as pump sources to efficiently convert electrical energy into light energy and stimulate electron transitions in solid laser gain media to generate stimulated radiation. In this process, through the frequency selection of the resonant cavity, the laser is continuously amplified in the cavity, and finally forms a stable and continuous green laser output. This is a 532nm 5mW DPSS laser module. The operating voltage is DC 5V. The spot quality is very good, and the divergence angle is also very small. Beam Divergence is less than 1 mrad. We can customize the modules according to your requirements.  The spectru

 The 40dBm ytterbium-doped fiber amplifier uses advanced ytterbium-doped fiber as the gain medium. Ytterbium is widely used in fiber amplifiers due to its unique energy level structure and efficient energy conversion characteristics. When pump light (usually high-power laser) is injected into ytterbium-doped fiber, ytterbium atoms absorb the energy of the pump light and undergo energy level transitions. Subsequently, when the optical signal passes through the fiber, the ytterbium atoms are stimulated to radiate photons of the same frequency as the signal light, thereby amplifying the optical signal. It is a 1030~1070nm Ytterbium-doped fiber amplifier. The saturated output power is 40dBm @0dBm input. The 40dBm YDFA is a high-power amplifier, with an additional Monitor interface. The Monitor is used to monitor or synchronize signals with low power. And it has built-in cooling fan. Configured with RS2323 interface, available software or control command YDFA. It supports two working modes
