We report on a new concept of credit card-sized free-space Yb:KYW laser cavity designed to generate femtosecond pulses at a GHz repetition-rate. Optical components are assembled directly, without mounts, inside slots fabricated by direct laser writing and chemical etching in a rigid fused-silica substrate, ensuring a very precise pre-alignment. The alignment fine-tuning is provided by one-time actuators fabricated within the glass substrate itself, which are remotely activated using femtosecond laser-induced micro-deformation in the bulk, ensuring a stable and lasting lasing operation. As a proof-of-concept, efficient CW and SESAM-enabled passive mode-locking regimes are demonstrated.
