Summary: Laser processing of diamond is crucial for next generation microelectronic and quantum devices, but achieving low taper, high aspect ratio structures remains challenging. We studied the impact of pulse energy, pulse number, and irradiation profile on aspect ratio in diamond using 532 nm nanosecond laser machining. We achieved a maximum aspect ratio of 22:1 with 10,000 pulses during percussion hole drilling of diamond. Rotary assisted drilling with over 2 million pulse accumulations allowed us to reach average aspect ratios of 40:1 and up to 66:1. Additionally, we demonstrated the ability to obtain 0.1 degrees taper angles in 10:1 aspect ratio tubes using ramped pulse energy machining. We also investigated the effects of laser induced damage and found a 36% increase in tensile strain following strong laser irradiation. However, applying 600 degrees C heat treatment reduced the induced strain by up to 50% with significant homogenization of strain observed.

Summary: This study achieved a flat plane with small surface roughness below 0.1 μm for monocrystalline diamond using nanosecond pulsed laser irradiation and acid cleaning. The use of a square beam in top-hat mode resulted in a wider and flatter bottom micro-groove compared to a round beam in Gaussian mode. A two-step scanning method was proposed to overcome the limitations of normal side-by-side repetition of linear micro-grooving. This method allowed for the creation of a widely flat plane with small surface roughness and provided superior control over micro-groove depth.

Summary: In this study, properties of negatively charged nitrogen-vacancy (NV-) centers created during single crystal diamond growth on [113]-oriented substrates with N2O as a dopant gas using chemical vapor deposition (CVD) were investigated. The results showed that at moderate growth temperatures, dense NV- ensembles with high NV-/ N0s ratios and high creation yield can be achieved.

Summary: The digital control of the latest nanosecond pulsed wave fibre lasers enables high precision and flexibility in energy application during welding processes, leading to reduced heat input and improved welding quality. By studying parameters like peak power, pulse energy, and width, different pulse shapes and spatial profiles can be chosen to achieve specific welding depths independent of beam diameter. Research also shows that maintaining a constant balance between pulse power factor and interaction time allows for obtaining identical penetration depth but varied weld metal profiles with different system parameters.

Summary: Traditional offline surface inspections lead to significant wasted machine time, while utilizing machine learning algorithms combined with sensor features for real-time classification shows better results, but there is an issue with unbalanced datasets during model training. A method is proposed to differentiate abnormal wear regimes by only familiarizing ML algorithms with the distribution of acoustic emission signals related to the normal wear regime, achieving high accuracy during validation, which can effectively enable real-time condition monitoring and wear prediction.

Summary: Submicron β-Ga2O3 pillars exhibit exceptional room temperature plasticity under compression, with a transition from brittle to superior plasticity observed as the pillar size decreases. The critical diameter for the transition from brittle to ductile behavior is approximately 800 nm, and a second transition to superior plastic deformation is reported below 500 nm due to the activation of secondary mechanisms. These findings highlight the importance of crystallography in submicron plasticity in β-Ga2O3.

Summary: Wear of ultra-high-molecular weight polyethylene (UHMWPE) in joint implant applications increases with cross-shear but decreases with higher contact pressure. This study investigates the origin and influence of protrusions formed on the pin surface following multidirectional sliding. The results suggest that the protrusions consist of folded UHMWPE and have a higher hardness, providing protection to the surface and leading to anomalous wear behavior.

Summary: The Laser Power Bed Fusion (LPBF) process is highly valued by various industries. However, the process lacks repeatability and reproducibility due to pore formation and the probabilistic nature of defect formation, limiting its application in industries that require high-quality and defect-free workpieces. In order to overcome this issue, an acoustic monitoring system was developed using Convolution Neural Network (CNN) to classify the processing regimes with high confidence based on Acoustic Emission (AE) waves. By utilizing a well-chosen set of training conditions, the model is able to construct a complete processing map without additional experiments.

Summary: Light beams possess three types of angular momentum, namely spin angular momentum, extrinsic orbital angular momentum, and intrinsic orbital angular momentum. The interaction between these momenta leads to the spin-orbit interaction of light and topological effects. This study predicts a new topological effect resulting from the influence of extrinsic orbital angular momentum on spin angular momentum in converging asymmetrical light beams. It manifests as the transformation of linear polarized light into elliptically polarized light when an asymmetrical beam passes through the left or right half of the focal plane. The measured value of the topological circular amplitude anisotropy R was found to be R = +/- (0.60 +/- 0.08) x 10(-3). This new effect contributes to our understanding of light and has potential applications in developing sensors in optics.

Summary: Due to the complexity of resolving object form and pose in images, new vision algorithms prioritize identification and perception over accurate coordinate measurement. However, the use of planar targets for coordinate measurement in vision systems has several drawbacks, including calibration difficulties and limited viewing angles. On the other hand, the use of sphere targets is infrequent in vision-based coordinate metrology due to the lack of efficient multi-view vision algorithms for accurate sphere measurements.
