In the past decades, microfluidic chips have been one of the hottest research topics in the
“lab-on-a-chip” field. However, it is still a challenge for design the perfect microchannels with …

摘要飞秒激光微加工技术具有加工精度高, 热效应小, 损伤阈值低以及能够实现真正的三维微
结构加工等优点, 这些特性是传统的激光加工技术所无法取代的. 首先回顾了激光微加工和超短 …

For the sensitive online and in situ detection of gaseous species, optical methods are ideally
suited. In contrast to chemical analysis, no sample preparation is necessary and therefore …

Compared with polymer-based biochips, such as polydimethylsiloxane (PDMS), glass
based chips have drawn much attention due to their high transparency, chemical stability …

A new method for fabricating microchannels for microfluidic applications on soda-lime glass
has been developed. It consists of a combination of a laser direct write technique for …

Massive pathological outbreaks have frequently impacted global risk, emphasizing the
necessity for on-site sample analysis techniques that are rapid, reliable, and responsive to …

Damage threshold of crystals SiO2 and YAG against 60–900fs, 800nm laser pulses are
reported. The breakdown mechanisms were discussed based on the double-flux model and …

A polypropylene (PP) film was ablated using a femtosecond laser with a center wavelength
of 785nm, a pulse width of 184fs and a repetition rate of 1kHz. Increments of both the pulse …

A compact intrinsic fiber Mach-Zehnder interferometer (MZI) is proposed and experimentally
demonstrated by incorporating a micro air-cavity ablated by femtosecond laser irradiation. A …

This paper presents a maskless micromachining process that can reform or reshape a
section of an optical fiber into a complex 3-D photonic microstructure. This proposed …
