IdealPhotonics' Nd:YVO4 fiber amplifier, a fiber-coupled amplifier based on Nd:YVO₄ crystal as the gain medium, excites a 1064 nm laser at 808 nm pump and couples it to the fiber system. It features high gain, low threshold voltage, and excellent thermal stability, specifically designed to provide seed light amplification and brightness enhancement for high-power fiber lasers.Through a crystal-fiber hybrid structure, it achieves >30 dB high-gain amplification in the 1064 nm band, while also possessing a wide absorption bandwidth (808±10 nm), low pump threshold (<1 W), and excellent thermal conductivity (5.23 W/m·K), making it a key preamplifier for improving brightness and stability in high-power fiber laser systems.
