PRISM Fiber Laser Module
Figure 5 redPOWER PRISM FL Module Key Features
A schematic block diagram of the PRISM FL Module is shown in Figure 5. The PRISM FL
Module is represented by the red rectangle and the cooling water circuit is indicated
schematically in blue.
o Optical Engine
The heart of the PRISM FL Module is the optical engine based on SPI Lasers’
proprietary GTWave
®
active fiber technology. GTWave takes the optical power of the
pump diodes to generate the high beam quality output of the QUBE Fiber Laser. It
requires no optical or mechanical adjustments.
o Pump Diodes
The pump diodes provide the power to the optical engine. Their high reliability means
that they will last for the life of the QUBE Fiber Laser
o Pump Drivers
The pump drivers control the drive current to the pump diodes allowing the output
power level of the QUBE Fiber Laser to be adjusted to different CW levels and to be
modulated over the specified power and frequency ranges.
