摘要

我们展示了在单级块状多通室（MPC）装置中通过后压缩掺钕皮秒激光器产生 350 fs 脉冲的过程。通过对光路的精心设计和精确校准，实现了创纪录的 125 次通过，使光谱展宽因子达到 16，脉冲压缩因子达到 27.1。据我们所知，这是首次从单级 MPC 压缩后掺钕皮秒激光设备中发射出 300 fs 级脉冲宽度。事实证明，它也适用于激光加工。

Sub-350 fs Pulse Generation via Nonlinear Compression With an Nd-Doped Picosecond Laser

We demonstrate the generation of 350 fs pulse by post-compression of a neodymium (Nd)-doped picosecond laser within a single stage bulk multi-pass cell (MPC) device. By meticulous design and precise alignment of the optical path, a record-high number of 125 passes is implemented, resulting in a spectral broadening factor of 16 and a pulse compression factor of 27.1. To the best of our knowledge, this represents the first instance of a 300-fs class pulse width being emitted from a single-stage MPC post-compression Nd-doped picosecond laser device. It also has been proven to be applicable for laser processing.

期刊介绍： IEEE Photonics Technology Letters addresses all aspects of the IEEE Photonics Society Constitutional Field of Interest with emphasis on photonic/lightwave components and applications, laser physics and systems and laser/electro-optics technology. Examples of subject areas for the above areas of concentration are integrated optic and optoelectronic devices, high-power laser arrays (e.g. diode, CO2), free electron lasers, solid, state lasers, laser materials'' interactions and femtosecond laser techniques. The letters journal publishes engineering, applied physics and physics oriented papers. Emphasis is on rapid publication of timely manuscripts. A goal is to provide a focal point of quality engineering-oriented papers in the electro-optics field not found in other rapid-publication journals.
