1. Novel beam shaping and computer vision methods for laser beam welding
Sammanfattning : Laser beam welding has been widely applied in different industrial sectors due to its unique advantages. However, there are still challenges, such as beam positioning in T-joint welding, and gap bridging in butt joint welding,especially in the case of varying gap width along a joint. LÄS MER
2. Diffractive optics : applications and beam-shaper design
Sammanfattning : .... LÄS MER
3. Investigation of Melt Pool Thermo-hydrodynamic Behaviour inLaser Beam Welding ofTi-6Al-4V through Numerical Simulation
Sammanfattning : Laser is an efficient and widely used heat source in metal processing suchas welding and additive manufacturing. It has some great advantages compared to the other conventional heat sources like electron beam and arc namely: ability of handling complicated joint geometries and producing large components.

4. Transverse mode and beam control in vertical-cavity surface-emitting lasers
Sammanfattning : .... LÄS MER
5. Diffractive Optics Design
Sammanfattning : Diffractive optical elements (kinoforms) change the way light propagates, and can perform very complex tasks. They can split an incident beam into any number of outgoing, and possibly focused, beams (fan-out). LÄS MER
