Multi-material additive manufacturing provides a new route for fabricating components with
tailored physical properties. Laser-based powder bed fusion (L-PBF), also known as …

The rapid expansion of femtosecond (fs) laser technology brought previously unavailable
capabilities to laser material processing. One of the areas which benefited the most due to …

In our work, passively mode-locked and Q-switched Er-doped fiber lasers (EDFLs) based on
titanium disulfide (TiS2) as a saturable absorber (SA) were generated successfully. Stable …

Nowadays, ultrafast laser welding has been widely used in chip labs, microelectronic
systems (MEMS), and micro-medical implantable devices, etc. The welding of the non …

Ceramics are difficult to machine into complex shapes due to their high hardness and
brittleness. In practical applications, ceramics often need to be jointed to themselves or …

The ability to weld metals and insulators is widely required in aerospace, sensors and Micro-
electro-mechanical systems (MEMS). Femtosecond laser welding is a precise and clean …

The position and posture of the optical components in the optomechanical systems require
to be adjusted before connection, so a certain gap between optics and metal base is needed …

Transparent hard and brittle (THB) materials have generated significant interest due to their
excellent properties, such as wide spectral transmittance, heat resistance, chemical inactivity …

High shear strength laser welding of glass-to-metal connections are significant in various
areas. However, ultrafast laser processing methods are high cost and demanding, while …

Advances of laser welding technology of glass by continuous wave (CW), ns pulse, and
ultrashort pulse (USP) lasers are overviewed in the past two decades from scientific and …
