The IMPULSE-HE is the next-generation laser in the IMPULSE family, delivering higher pulse energy while maintaining the key features that have made the original Model IMPULSE renowned. Built upon an advanced all-diode-pumped, Yb-doped fiber oscillator/amplifier system, it offers variable pulse energies exceeding 70μJ, with user-adjustable repetition rates ranging from single-shot to 25MHz.
At its core, IMPULSE-HE revolutionizes mode-locked oscillator/amplifier technology. By integrating a Yb-doped fiber-oscillator/fiber-amplifier architecture, it combines the low-noise stability of solid-state operation with the superior spatial mode quality of fiber lasers.
Designed as a compact, robust, all-in-one femtosecond pulse source, IMPULSE-HE ensures ease of operation, exceptional stability, and reliability. With fully computer-controlled parameters, it seamlessly interfaces with workstations or experimental setups. Remote accessibility enables comprehensive control over all laser parameters and diagnostics.
