Paper Abstract

The majority of fiber laser volume applications are price sensitive. Therefore, the availability, quality and cost of singleemitter- based pumps will have decisive impact on the breadth of further fiber lasers' acceptance. Availability and cost should not come in expense of further improvement in pumps' performance and reliability. Here we report on optimized high-power and high-brightness wavelength stabilized CW devices. Performance of CW pumps rated for 100W and 50W power is discussed. Pumps launch over 98% output power into a spectral window of 975±0.5nm at driving currents ranging from 2A to 12A and the heatsink temperature variation from 20°C to 50°C. Such performance qualifies these wavelength-stabilized pumps for use in many air-cooled and special applications.
