The domestic glass laser (ie laser tube) and the imported laser have basically the same processing purpose and application. There are big differences in appearance, structure, lifespan, and performance. There is also a big difference in price. For the same power, imported lasers are about dozens of times higher than domestic lasers. (The lifespan is also very different. Imported CO2 lasers can be used repeatedly, while domestic glass laser tubes are generally used for one-time use.) Therefore, domestic glass lasers have been recognized by customers at home and abroad because of their low price and economy.
