We demonstrate how an objective measure can be employed in the widely employed rubber hand illusion paradigm. This measure is obtained by modifying the well-established crossmodal congruency task. This task allows the investigation of multisensory processes which are critical for modulations of body representations as in the rubber hand illusion.

A protocol to detect and automate mode locking in a pre-adjusted nonlinear polarization rotation fiber laser is presented. The detection of a sudden change in the output polarization state when mode locking occurs is used to command the alignment of an intra-cavity polarization controller in order to find mode-locking conditions.

An all laser procedure is proposed in the endothelial transplant. The surgical technique is based on the use of a femtosecond laser to prepare the donor tissue. Laser welding technique is then used to secure the donor endothelium in the correct position.
FAQs
A focused laser pulse rapidly heats or vaporizes a localized region of the donor layer. This sudden energy deposition generates pressure at the interaction site, propelling material across the small donor-receiver gap. The transfer therefore depends on concentrating energy at the intended location while maintaining controlled spacing and alignment.
Preserving composition is important when a deposited feature must retain the functional identity of its source material. The approach supports patterned placement of polymers, metals, ceramics, and other engineered materials while maintaining the donor’s composition, making material integrity a central outcome alongside spatial placement accuracy.
Energy, alignment, and gap size are the key controllable conditions identified for effective transfer. Laser energy must produce the local heating or vaporization needed to generate propulsion, while alignment determines whether the material reaches the intended position. The small gap also supports a controlled path from donor to receiver, linking process conditions to pattern accuracy.
A basic workflow begins by positioning the donor layer and receiving substrate with a small gap between them. The laser is then focused on the selected donor location, and a controlled pulse drives material onto the corresponding receiver area. Repeating this localized operation enables patterned deposition for functional structures rather than unrestricted coating.
In engineering, Congruent laser transfer is relevant when fabrication requires both spatial accuracy and material integrity. The overview identifies microscale manufacturing, electronic device fabrication, sensor production, and additive manufacturing as use cases. Across these settings, the technique can place selected material in patterned structures while retaining the composition associated with the donor.
Material selection can extend across polymers, metals, ceramics, and other engineered materials, so the approach is not limited to a single class of donor. The important engineering question is whether the chosen material can be processed under controlled laser energy and transferred across the gap while preserving composition and intended placement.
