The present application relates to a laser marking system (100) comprising a laser (110) configured to produce a laser beam, a marking head (130) configured to project the laser beam onto a target, and a negative curvature hollow core fiber (120) configured to transmit the laser beam from the laser (110) to the marking head (130).

The present disclosure provides methods and systems for composite-to-metal hybrid bonded structures compromising the laser surface treatment on titanium alloys to promote adhesive bond performance. For example, a computer may be programmed to set a laser path corresponding to a predetermined geometric pattern. A laser may be coupled to the computer and apply a pulsed laser beam to a contact surface of the titanium alloy along the predefined geometric pattern. The laser may generate an open pore oxide layer on the contact surface of the substrate with a thickness of 100 and 500 nm. The open pore oxide layer may have a topography corresponding to the predefined geometric pattern. The topography may contain high degree of open pore structure and promote adhesive bond performance. Adhesive, primer or composite resin matrix may fully infiltrate into the open pore structures. Adhesive and composite laminate may co-cure to form composite-to-titanium hybrid bonded structures.

The present invention is directed to an improved fishing rod guide. In one embodiment the improved fishing rod includes superhydrophobic metal guides. The superhydrophobic metal guides make it possible for fishing line, including, for example, fly fishing line and conventional fishing line, to move through the guides with less weight and drag due to water and ice accumulation, allowing for significantly greater distance and ease in casting. Additionally, the decrease in friction between the fishing line and line guides help extend the life of the fishing line.
