Laser-Scribed Graphene Electrodes for Aptamer-Based Biosensing
ACS Sensors, 2017Graphene as a transducer material has produced some of the best-performing sensing approaches to date opening the door toward integrated miniaturized all-carbon point-of-care devices. Addressing this opportunity, laser-scribed graphene (LSG) electrodes are demonstrated here as highly sensitive and reliable biosensor transducers in blood serum analysis.

Laser scribed graphene for energy storage application
2015 Opto-Electronics and Communications Conference (OECC), 2015In this paper, a method of laser reduction to produce reduced graphene oxide is explored. Results show that the resultant graphene layer, together with proper electrolyte, can be used to fabricate high energy density supercapacitors.

Scribing characteristics of ceramics with Nd:YLF laser
SPIE Proceedings, 2003The laser scribing process is a perspective technique to produce grooves on brittle materials. In this study, we investigated the microscribing of Al 2 O 3 ceramics with a diode-pumped Nd:YLF laser. The groove width, the groove depth and the debris height were chosen as evaluation items of the processing.

Advanced Laser Scribing for Emerging LED Materials
Additional Conferences (Device Packaging, HiTEC, HiTEN, and CICMT), 2011Lasers are becoming increasingly important in today's LED revolution and are essential for increasing the efficiency and reducing manufacturing cost of LEDs. Diode pumped solid state lasers excel in scribing horizontal type LEDs on sapphire, silicon, silicon carbide, III-nitrides (gallium nitride and aluminum nitride), as well as III-V semiconductors ...

Glass scribing by a UV picosecond laser
ICALEO 2018: 37th International Congress on Applications of Lasers & Electro-Optics, 2018An ultraviolet (UV) picosecond laser (Nd:YVO4) is used to scribe a soda lime glass substrate. The damaged surface morphology and the corresponding interaction mechanism between the laser and glass are investigated and analysed. According to experimental results, groove shape is only produced at relatively high scanning speeds (200-250 mm/s) by proper ...

MOPA pulsed fiber laser for silicon scribing
Optics & Laser Technology, 2016Abstract A 1064 nm master oscillator power amplifier (MOPA) pulsed fiber laser is developed with flexible control over the pulse width, repetition frequency and peak power, and it is used to investigate the dependence of mono-crystalline silicon scribe depth on the laser pulse width, scanning speed and repeat times. Experimental results indicate that

Laser Scribing of W-textured ZnO Substrates Using Green Laser
MRS Proceedings, 2013ABSTRACTThin-film silicon solar cells have been attracted a lot of intention as low-cost solar cells. One of the most important technologies for improving their performances is light trapping. We have demonstrated the high potential of double-textured zinc oxide (ZnO) thin films used as front transparent conductive oxide (TCO) films due to further ...

Laser scribing of thin film solar cells
PICALO 2010: 4th Pacific International Conference on Laser Materials Processing, Micro, Nano and Ultrafast Fabrication, 2010Laser scribing of thin film solar cells for TCO, absorber and top contact layers with nanosecond laser is described in this paper. P1 process (TCO scribing) is performed with 355nm and 1064nm lasers; P2 (absorber) and P3 (top contact) patterning with 532 nm laser are conducted.
