During one discussion with a customer, Larcombe decided that instead of simply explaining the theory, it would be interesting to analyze the results and experiences of users over the last three years. During this time, more than 35 fiber laser cutting machines have been sold by the company in the UK alone. Fiber lasers Briefly, fiber laser light is created by banks of diodes. The l...
