10 kw fiber laser is only 10 years behind IPG Photonics.Iran Center for Laser Science and Technology
1: 5KW high power thin disk laser
2: Fiber laser with a power of 10 kW, welding power of 5 mm steel at a speed of 5 to 6 minutes per hour
3: Tandem fiber laser
A record-high power level for a fiber laser has recently been achieved by IPG with an indirect pump scheme. The article explains the reasoning behind this.
