Jasper Flex: High Power Femtosecond Fiber Laser
Jasper Flex is our new high-power femtosecond laser for microprocessing. Its compact size makes it even easier to use and to integrate into existing systems. It delivers pulses with a maximum energy of 30 uJ at up to 1 MHz repetition rate. The user-configurable burst mode brings new capabilities in industries manufacturing consumer electronics, integrated photonics, and displays.
We believe that the most important part of the high-power laser is a femtosecond oscillator. It is the heart of our every system. Jasper Flex is based on Fluence’s unique technology of truly all-fiber, SESAM-free oscillator that was tested to operate at 40 g vibration. Additionally, it was assessed in a vast range of temperatures spanning over 50 deg C. The oscillator together with a fiber preamplifier creates a monolithic construction immune to misalignment. This defines the robustness of the Jasper Flex system.
