Jasper Flex: High Power Femtosecond Fiber Laser

Jasper Flex – 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, 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 the most important part of the laser is a femtosecond oscillator, which is the heart of every system. Jasper Flex is based on Fluence unique technology of truly all-fiber, SESAM-free oscillator that was tested to operate at 40g vibration and in a vast range of temperatures spanning over 50 deg C. The oscillator together with a fiber preamplifier create a monolithic construction immune to misalignment defining the robustness of the Jasper Flex system.
