We propose a new architecture to realize a monolithic multi-disk laser by the surface activated bonding (SAB). This multiple thin-disk or micro-chip gain medium base distributed face cooling (DFC) structure has an excellent thermal management with high-gain to realize the high-power and high-field laser with compact system. With Nd:YAG/sapphire DFC-chip, a sub-nanosecond 21.5mJ, 32.5 MW pulsed microchip laser was achieved. Today, multi-J class output energy DFC-chip amplification at room temperature operation could be realized. Nonlinear optics could expand the potential of high-brightness laser source. A large aperture quasi-phase matching (QPM) device of LA-PPMgLN enable the high-efficient optical generation of narrowband THz waves for the newly proposed dielectric particle acceleration (THz-DLA). These downsized and modularized tiny integrated lasers (TILA) promise the “Giant Micro-photonics“ extremely high-brightness lasers to open up the new science, such as laser driven electron accelerator toward table-top XFEL, and innovation by the compact power laser.
