Coherent Axon laser won the 2023 Business Innovation Award from the British Physical Society

       近日，从江苏通用半导体有限公司传来消息，由该公司自主研发的国内首套的8英寸碳化硅晶锭激光全自动剥离设备正式交付碳化硅衬底生产领域头部企业广州南砂晶圆半导体技术有限公司，并投入生产。 图：8英寸SiC晶锭激光全自动剥离设备       该设备可实现6英寸和8英寸碳化硅晶锭的全自动分片，包含晶锭上料、晶锭研磨、激光切割、晶片分离和晶片收集，一举填补了国内碳化硅晶锭激光剥离设备领域研发、制造的市场空白，突破了国外的技术封锁，将极大地提升我国碳化硅芯片产业的自主化、产业化水平。       该设备年可剥离碳化硅衬底20000片，实现良率95％以上，与传统的线切割工艺相比，大幅降低了产品损耗，而设备售价仅仅是国外同类产品的1／3。       近年来，碳化硅功率器件在大功率半导体市场中所占的份额不断提高，并被广泛应用于新能源汽车、城市轨道交通、风力发电、高速移动、物联网等一系列领域...

Figure: Experimental setup.Quantum memory that relies on quantum band integration is a key component in developing quantum networks that are compatible with fiber optic communication infrastructure. Quantum engineers and information technology experts have yet to create such a high-capacity network that can form integrated multimode photonic quantum memories in communication frequency ban...

In most cases, devices that are part of so-called smart homes have become a part of our lives. These appliances have a significant impact on our comfort level and contribute to daily household chores, such as cleaning. There are many products in the market that have paved the way in this regard, but the amount we usually have to pay for them effectively prevents us from purchasing.Of course, we ca...

Recently, the State Key Laboratory of Intense Field Laser Physics of the Chinese Academy of Sciences Shanghai Institute of Optics and Fine Mechanics has made new progress in generating intense field terahertz waves based on Yb laser pumped organic crystals. The relevant research results were published in Applied Physics Letters under the title "Efficient strong field THz generation from DSTMS crys...

Starting from June 20th, The Creativity Falcon 2 laser cutting machine will also be launched in Germany, equipped with a new 60W laser head. With this ability, fully encapsulated equipment can now also be carved into steel. High power is achieved through twelve 5-watt laser diodes, whose beams are combined with each other. This will make it possible to cut 22mm thick lime wood and 30mm thick or...
