PHAROS femtosecond lasers combine multi‑millijoule pulse energy and high average power, featuring a robust optomechanical design optimized for both scientific and industrial applications. The thermally stabilized and sealed design ensures seamless integration into various optical setups and machining workstations, delivering exceptional laser lifetime and stable operation across varying environments.

PHAROS provides unparalleled versatility, covering applications that would typically require multiple laser systems. Its key tunable parameters include pulse duration (100 fs – 20 ps), repetition rate (single-shot – 1 MHz), pulse energy (up to 4 mJ), and average power (up to 20 W).

The built-in pulse picker enables a pulse-on-demand mode, further enhancing operational flexibility. Additionally, the versatility of PHAROS femtosecond lasers can be further extended by a variety of options, including carrier-envelope phase (CEP) stabilization, repetition rate locking to an external source, automated harmonic modules, and optical parametric amplifiers.
