Abstract

We demonstrate a diode-pumped Cr:LiSAF laser with controllable and reliable fast switching between its continuous-wave and mode-locked states of operation using an optically-addressed semiconductor Bragg reflector, permitting dyed microspheres to be continuously trapped and monitored using a standard microscope imaging and on-demand two-photon-excited luminescence techniques.

摘要

我们展示了一种二极管泵浦的Cr:LiSAF激光器，它使用光寻址半导体布拉格反射器，可在连续波和锁模工作状态之间进行可控且可靠的快速切换，从而能够使用标准显微镜成像和按需双光子激发发光技术对染色微球进行连续捕获和监测。
