“Micro Solid-State Photonics” based on the micro domain structure and boundary controlled materials, opens new horizon in the laser science. The engineered materials of micro and/or microchip solid-state, ceramic and single-crystal, lasers can provide excellent spatial mode quality and narrow linewidths with enough power^1-5). High-brightness nature of these lasers has allowed efficient light-matter interaction and wavelength extension by nonlinear frequency conversion: the world first YAG ceramic microchip laser ignited car ^6-8), highly efficiency broad frequency conversions from the wavelength of 118 nm VUV⁹⁾ until MIR of 11 μm^4),10), in addition THz to millimeter wave of 0.1-0.8 mm^11),12) , and so on. Here, the quasi phase matching (QPM) is an attractive technique for compensating phase velocity dispersion in frequency conversion. Lately, we propose a new architecture to realize a monolithic multi-disk laser by the inter layer assisted surface activated bonding (il-SAB)¹³⁾. This multiple thin-disk or chip gain medium for distributed face cooling (DFC) structure can manage the high-power and high-field laser with high-gain compact system. Besides, QPM-structured crystal quartz constructed by multi-plate stacking could be promising as a high-power and reliable VUV frequency conversion devices¹⁴⁾. These downsized and modularized tiny integrated lasers (TILA) promise the extremely high-brightness lasers to open up the new science, such as laser driven electron accelerator toward table-top XFEL with RIKEN SPring-8 Center^11),15),16), and innovation by the compact power laser cooperation with TILA consortium¹⁷⁾ (Fig. 1).
