A fiber laser typically lasts for thousands of hours before it needs to be replaced. This is because fiber lasers have a solid-state design, which means that there are no moving parts that can wear out over time.
In addition, the materials used in fiber lasers are highly durable, allowing them to withstand extreme temperatures and harsh operating conditions. With proper maintenance and care, a fiber laser can be expected to last for many years, providing reliable performance and consistent results.
Overall, fiber lasers are a cost-effective and efficient solution for a wide range of industrial and scientific applications.
