Abstract

We present a thorough investigation of surface deformation and thermal properties of high-damage threshold large-area semiconductor saturable absorber mirrors (SESAMs) designed for kilowatt average power laser oscillators. We compare temperature rise, thermal lensing, and surface deformation of standard SESAM samples and substrate-removed SESAMs contacted using different techniques. We demonstrate that for all cases the thermal effects scale linearly with the absorbed power, but the contacting technique critically affects the strength of the temperature rise and the thermal lens of the SESAMs (i.e. the slope of the linear change). Our best SESAMs are fabricated using a novel substrate-transfer direct bonding technique and show excellent surface flatness (with non-measureable radii of curvature (ROC), compared to astigmatic ROCs of up to 10 m for standard SESAMs), order-of-magnitude improved heat removal, and negligible deformation with absorbed power. This is achieved without altering the saturation behavior or the recovery parameters of the samples. These SESAMs will be a key enabling component for the next generation of kilowatt-level ultrafast oscillators.

Abstract

Background A blue LED photocoagulator, named EMOLED, has been designed. The device emits in the blue-violet region of the light spectrum. When irradiating a bleeding wound, the light is absorbed by the haemoglobin and converted in a temperature enhancement, thus inducing coagulation. In this work we present a study on the healing process in superficial wounds treated with EMOLED. Methods The compact device was tested on superficial skin wounds in animal model. Four mechanical abrasions were produced on the back of 10 Sprague Dawley rats: two were treated with the blue-LED device, while the other two were left to naturally recover. During irradiation, the device was kept in a slow motion above the bleeding site, in a non-contact configuration. Temperature control was performed during treatment. The 30s treatment was performed once and then the animals underwent an 8 days follow up study. Samples from treated and untreated sites and from a healthy control underwent non-linear microscopy analyses, histology, immunofluorescence analysis. Results Temperature monitoring during treatment evidenced a maximum value of about 48°C. Visual observations, non-linear microscopic imaging, as well as histology and himmuno-fluorescence analyses demonstrated no adverse reactions neither thermal damages in both abraded areas and surrounding tissue. A reduced fibroblast and myofibroblast density was observed in the treated wounds. In treated wounds the collagen fiber bundles show typical dermal collagen architecture; the collagen organization was more isotropic; collagen fiber bundle size is in average smaller in the untreated with respect to the treated wounds. Conclusions These preliminary results evidenced a faster healing process and a better-recovered skin morphology: the treated wounds show a reduced inflammatory response and a higher, isotropic, collagen content.
