The posting

1. 紫外激光器整机开发 - 负责紫外纳秒及皮秒激光器的技术方案设计与整机开发，从概念验证到样机定型。 - 谐振腔设计与仿真：ABCD 矩阵与模式匹配计算、热透镜与热应力评估、增益介质与泵浦方案选型、腔型稳定性设计。 - 非线性变频设计：晶体选型（LBO / BBO / KTP 等）、相位匹配与温度/角度容差、走离效应与群速失配控制、腔内与腔外变频方案的取舍与论证、变频效率与光束质量的平衡。 - 样机装调与性能标定：输出功率与效率、光束质量 M²、脉宽与脉冲能量、功率稳定性与长时漂移、光谱、指向稳定性、偏振等指标的测试与达标。 2. 实验设计与可靠性验证 - 搭建并维护紫外相关实验平台，独立设计 DOE，用数据而非经验推动方案收敛。 - 主导紫外特有的失效与寿命研究：UV 诱导光学元件退化、镀膜激光损伤阈值（LIDT）、晶体潮解与雾化、有机物污染与碳沉积、吹扫/氮气环境控制方案。 - 组织加速寿命试验与高低温、湿热、振动等环境试验，建立失效分析（FA）到设计改进的闭环。 3. 二级物料深度开发与降本 - 对核心 BOM 建立技术规格与验收标准，覆盖： - 非线性晶体与 UV 光学元件（晶体、镜片镀膜、隔离器、扩束/整形元件） - 泵浦源与电源模块（泵浦 LD、驱动电源、TEC 与温控） - 精密结构件、腔体机械件与水冷/散热组件 - 主导二供与国产替代的技术导入：定义关键参数与判据，编写来料检验方法（透过率与吸收、波前与面型、LIDT、损耗、寿命、一致性），组织对比测试与样件评估。 - 按"样件验证 — 小批量试产 — 量产切换"三阶段推进物料导入，输出技术风险评估与切换判据，避免"为降本牺牲可靠性"。 - 与采购、SQE、供应商研发团队协同，拆解 BOM 成本结构，识别成本主因并制定可量化的降本路径与时间表；对达成的降本幅度与性能影响负责。 - 参与关键供应商的技术审核与联合开发，提升对方工艺能力而非单纯压价。 4. 量产转化与产线支持 - 参与 DFM / DFA 评审，设计装调 SOP、工装夹具与测试台，降低对个人手艺的依赖。 - 推动一致性与良率提升，处理产线技术异常与客户端质量问题的根因分析。 - 沉淀设计规范、技术标准与专利，参与技术方案评审与内部培训。

  • 学历专业：光学工程、光电信息、物理电子学、激光技术、应用物理等相关专业，本科及以上。
  • 经验年限：5 年以上紫外激光器（固体紫外、UV 纳秒/皮秒，或紫外光纤/混合方案）研发与生产经历；至少完整主导或深度参与过 1 款紫外激光器从设计到量产的全过程。
  • 原理深度：对紫外激光产生有系统性理解——倍频/和频过程、相位匹配（临界与非临界）、走离与群速失配、变频效率的理论与工程上限、UV 波段材料与镀膜的退化机理，能从原理层面判断方案的可行边界，而不只是照搬既有腔型。
  • 实测能力：精通紫外光电测试与仪器使用：功率/能量计、光束质量分析仪、脉宽测量（自相关仪或快探 + 高带宽示波器）、光谱仪、稳定性长跑与数据分析。
  • 装调经验：具备洁净环境下紫外光学装调的实际动手经验，理解 UV 污染控制与洁净度要求。
  • 物料与成本经验：有二级物料开发、国产替代或供应商技术导入的实操经验，能独立编写物料技术规格书与验收方法，理解量产导入的验证节奏。
  • 工作方式：动手能力强、数据驱动、结论实事求是；能在信息不完整时设计实验去获取事实，而不是靠推断下判断。

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
