Lecture topic:《The influence of SLM on the flow rate and cooling performance of SLM-fabricated cooling channels

Summary:Selective laser melting, SLM has been widely used in the fabrication of conformal cooling molds. However, the SLM-fabricated cooling channels are different from cooling channels fabricated by conventional drilling process. Here, we designed and manufactured an experimental system to measure the fluid flow rate and cooling performance of the internal cooling channels. Experimental comparison of flow rate and cooling performance was conducted for SLM-fabricated and conventionally-drilled channels. The achieved results may provide reference to the design of conformal cooling molds.

Lecture topic:《High-Brilliance and High-Efficiency: High Power Diode Laser for Different Applications

Summary:High-power laser bars, laser arrays and single emitters especially in the GaAs-based emission wavelength range between 760 nm and 1060 nm are now a common light source for many industrial, medical and science applications. In the industrial material processing such laser diodes are used for the direct material processing or as pump sources for solid state laser (disc-, rod- and slab laser) and for fiber lasers. Laser diodes in this wavelength range are also wide spread used as light sources for various medical applications such as aesthetics (hair and wrinkle removal, liposuction), photo-dynamic therapy (microsurgery) and surgical treatment. There is also a great interest on high power pulse operation laser bars for the laser ignition and fusion applications. All these applications require a continuous improvement of laser diodes for reliable operation at high output powers densities and simultaneously high electrical-to-optical efficiencies and at the end for attractive costs. JENOPTIK presents an overview of the status and recent progress in the development of highly efficient and powerful laser devices for continuous and pulse operation, emitting in a wide wavelength range between 760 nm and 1060 nm with a focus on brightness, reliability and production stability.

Lecture topic:《Fish-bone nanostructure biosensor

Summary:In recent years, the surface plasmon devices have a great progress, such as surface plasmon biosensor, the function of it is close to the clinical and practical applications. Also, the corresponding commercial products are launched for research and biomedical industry. Nowadays, the highly sensitive and miniature-sized surface plasmon device is still the trends of next-generation applications. Thanks to the development of electron-beam lithography (EBL) and focused-ion-beam lithography (FIB), we could manufacture the sub-micron or nano structures which can guide the surface plasmon polariton (SPP) to one direction. Furthermore, these nano structures not only produce unidirectional SPP, but have the potential to be a surface plasmon device. In this program, an innovative, miniature plasmon heterodyne interferometric sensor is proposed. We will use a fishbone structure which is induced by a pair of orthogonal circularly polarized light will produce a unidirectional SPP. Owing to the characteristic of the fishbone structure, we are able to design the position of the structures which can combine the unidirectional SPPs. Then, a set of well-designed fishbone structures and Zeeman laser are utilized to produce a set of unidirectional SPPs with a beat frequency. Thus, the structures are a miniature surface plasmon heterodyne interferometer and the sensitivity will reach up to 10-7 RIU. We can use these structures as a surface plasmon heterodyne interferometric sensor for measuring the phase difference and calculate the index difference of samples. This innovative sensor has the features: 1. scale-down optical path, 2. enhanced sensitivity and 3. low-concentration measurement. Thus, we could apply this innovative sensor on single-molecular detection, biomedical sensing, etc. Moreover, it could combine with florescent molecules as a biosensor with high sensitivity.

Lecture topic:《Laser induced back wet/dry etching

Summary:Due to the good transparency of glass, it is difficult to be directly fabricated by lasers. Currently, a method of applying UV lasers is used for glass processing in the industry. Laser-induced backside wet etching (LIBWE) technology overcomes this shortcoming. The use of the LIBWE system for the etching of transparent substrates (glass) results in near-optical surfaces. The production of high aspect ratio structures can also be achieved through LIBWE processing and manufacturing. Thus this technology has high industrial applicability. In addition to discussing the architecture of the LIBWE technology, this article briefly describes its working principle. Finally, the etching results of different LIBWE systems are introduced and the features of different LIBWE systems are compared. In the future, we hope that LIBWE technology will have the opportunity to be applied to other laser industries.
