Page 11: Description
Description The Koheras BOOSTIK HP system is a Continuous Wave Fiber Amplifier (CW) system. The amplifier produces ultra-bright, near-diffraction-limited, infrared laser light, delivered to a flexible output fiber and collimating optics. The amplifier contains reliable, high-brightness diode lasers that pump a double-clad, ErYb-doped or Yb-doped optical fiber. -
Page 12: Configuration Id
Note: Other applications for a BOOSTIK HP system include using it as a linear optics pump source (SHG, DFG, OPO) and for laser-based metrology. Configuration ID Koheras modules are defined by their configuration ID which includes the options. Refer to for a list of Koheras BOOSTIK HP configuration IDs. -
