Performance evaluation and design considerations of high-performance ytterbium-doped fiber laser system(invited)
摘要
Abstract
[Background]Ytterbium-doped fiber lasers are important tools for green intelligent manufacturing and are the preferred light source for contemporary high-energy laser systems.Focusing on performance,platforms scenarios,"three highs and three lows"performance characteristics such as high brightness,high efficiency,high robustness,miniaturization,light-weight and low cost of the fiber laser system need to be comprehensively considered.[Purpose]This study aims to propose two new metrics CSWpP(Cost-Size-Weight per unit Power)and CSWpB(cost-size-weight-brightness per unit Brightness),and elaborate on the relevant thoughts on reducing this metrics,which is particularly important to effectively evaluate the performance of the fiber laser system and improve its performance.[Methods]Firstly,based on the composition of the fiber laser system,parameters for evaluating the performance of the fiber laser system are given,with a focus on defining and calculating the comprehensive evaluation parameters CSWpP and CSWpB.Secondly,according to the characteristics of industrial fiber laser systems,the efficiency,heat,volume,and weight parameters of the optical,electrical,and thermal modules of the fiber laser are analyzed,and it is pointed out that the thermal control module is crucial for the lightweight and compactness of the laser system.The volume,weight and power consumption of fiber laser systems of different power levels are evaluated.Thirdly,several possible misunderstandings in the design and cognition of current fiber laser systems are analyzed.[Results]Finally,in order to reduce the CSWpP or CSWpB of fiber lasers for practical application scenarios,high-efficiency,low-heat production,wide-temperature range,strong heat resistance optical and overall design ideas are proposed,as well as a composite thermal management technology scheme of capacitance,conductivity,expansion,switching,storage and discharge,and a strong coupling integrated engineering design idea,in order to provide reference for the design of high-performance fiber lasers.[Conclusions]Therefore,more attention should be paid to and efforts should be made to reduce the CSWpP or CSWpB to achieve higher laser system performance.关键词
