受自然界塑造软生物材料以展示一系列光学功能的能力的启发，我们报告了飞秒激光致密化作为一种在普通水凝胶材料中产生体积或亚表面衍射光栅的新方法。我们用飞秒激光功率、速度和穿透深度来表征聚乙二醇二丙烯酸酯(PEGDA)水凝胶中实现致密化的加工范围，并表征相关的局部折射率(RI)的变化。RI变化便于在PEGDA内制造定制的体栅(平行线、栅格、正方形和环形栅格)。为了证明这种方法的广泛适用性，利用飞秒激光致密技术在苯基硼酸(PBA)水凝胶中产生线栅，众所周知，PBA水凝胶对pH变化有响应。在未来，这项技术可以用来将普通水凝胶转化为多组分生物光子系统。
Inspired by nature’s ability to shape soft biological materials to exhibit a range of optical functionalities, we report femtosecond (fs) laser-induced densification as a new method to generate volume or subsurface diffractive gratings within ordinary hydrogel materials. We characterize the processing range in terms of fs laser power, speed, and penetration depths for achieving densification within poly(ethylene glycol) diacrylate (PEGDA) hydrogel and characterize the associated change in local refractive index (RI). The RI change facilitates the fabrication of custom volume gratings (parallel line, grid, square, and ring gratings) within PEGDA. To demonstrate this method’s broad applicability, fs laser densification was used to generate line gratings within the phenylboronic acid (PBA) hydrogel, which is known to be responsive to changes in pH. In the future, this technique can be used to convert ordinary hydrogels into multicomponent biophotonic systems.
