Ultrafast lasers are key tools for micromachining and medical applications, but also in a growing numbers of domains like telecoms, aerospace and microwave photonics, which are currently limited by the lack of reliability of the lasers and the achievable repetition rate. Menhir Photonics has now successfully demonstrated and deployed real-turnkey ultrafast laser oscillators at 1.5 um and GHz repetition rate with an unprecedent robustness. Reaching now up to 2.5 GHz of fundamental repetition rate and the lowest phase noise and timing jitter on the market, the MENHIR-1550 was already qualified for Space. The latest development of the MENHIR-1550 at 2.5 GHz will be presented (first commercial product of its kind) as well as the newest applications that it enabled worldwide, in the fields of green-house gases monitoring from Space, very fast dual-comb spectroscopy or photonics analog-to-digital converter.
