The realization of compact laser-plasma accelerator (LPA) driven free electron lasers (FELs) has been attempted for nearly two decades, yet, difficult to overcome electron beam quality and stability issues prevented FEL lasing until recently. LPA based FEL is now demonstrated in both the self-amplif… [Phys. Rev. Lett. 136, 245001] Published Tue Jun 16, 2026
