488nm 2W CW Fiber Laser and Amplifier
Xiaoxiao Photonics is a company that develops, manufactures, and commercializes innovative fiber laser technologies. Its outstanding design represents a true breakthrough in the laser market, especially compared to other solidstate technologies. Our team is dedicated to combining stringent fiber laser specifications: high power, singlemode, singlefrequency, ultralow noise, to meet demanding applications. The unique allfiber architecture ensures reliability and enables efficient integration. The MOPA (Master Oscillator Power Amplifier) architecture with its 3buildingblock approach (seeder + HP amplifier + optical head) gives us the freedom to customize our products according to your application. This essential product delivers excellent beam quality (M² < 11) via an aircooled compact laser head. Different turnkey configurations are available: laser or amplifier. Our lasers combine advanced fiber laser specifications without compromising stability and reliability, making them an excellent tool to push the limits of your most demanding applications.
