1.题目:Spatiotemporal Mode-Locking in Lasers

摘要：The field of ultrafast science is built on a foundation of femtosecond pulse generation in mode-locked lasers.  All mode-locked lasers currently in use are based on resonators that support a single transverse spatial mode. The locking of longitudinal and transverse modes in a laser was demonstrated in 2017 [1]. This multimode or spatiotemporal mode-locking opens the possibility of three-dimensional shaping of ultrashort pulses inside a laser. The basic features of spatiotemporal mode-locking will be explained [2]. New opportunities in laser science, as well as possibilities for exploiting spatiotemporal pulse-shaping for high-performance instruments, will be described.

The talk will include a tutorial introduction to nonlinear pulse propagation in optical fiber.

2.题目：光学双向脑机接口技术

摘要：脑机接口作为革命性的神经工程技术，近年来受到广泛关注。但是，当前脑机接口性能提升仍存在未解的关键科学难题：（1）解码性能与记录通量、密度的关系？（2）是否存在特定类型的关键神经元？相较于其他脑机接口技术，基于光学显微与基因工程的光学脑机接口技术可同步实现在体神经活动的高通量读取与高分辨率调控，有望回答上述重大问题。然而，受限于脑组织的固有散射特性及显微系统的有限空间带宽积、机械惯性等约束，当前大尺度神经功能环路解析仍面临着诸多挑战。本报告将介绍本课题组在面向光学双向脑机接口技术方面的最新进展。
