Pulse width is an important parameter of the pulsed laser. The measurement result is an important factor affecting the single pulse energy. At present, biased photoelectric detectors are commonly used in industrial production and scientific research to test the pulse width, convert optical signals into electrical signals, and read the waveforms and related parameters through … Continue reading
A collaborative effort by Light Conversion, Vilniaus universitetas (Vilnius University), and Center for Physical Sciences and Technology (FTMC) have demonstrated a compact high-flux X-ray source based on irradiation of solid targets by gigahertz and megahertz bursts of femtosecond laser pulses. The simplicity and relative cost-effectiveness of the presented X-ray source makes it an attractive solution … Continue reading
MDL-III-xxx-SM series diode lasers from CNI Optoelectronics Tech(CNI) are specially designed for single-mode fiber (include PM), coupled with high power stability <0.5% and long term stability. These lasers are ideal for application in measurement, communication, spectrum analysis, and many other fields. Each laser has a single wavelength from 405 to 1683 nm. Output power varies … Continue reading
Microfluidic channel surface roughness might be a concern in direct femtosecond laser ablation, normally yielding an RMS value in the range of a few µm. One solution to improve this value is using the fs bi-burst regime. In an article, entitled “Fabrication of Microfluidic Tesla Valve Employing Femtosecond Bursts,” it is shown how fs-burst mode ablation … Continue reading
Did you know that CO2 lasers are used to create cutting-edge integrated circuits in your mobile phones? Extreme ultraviolet lithography (EUVL) systems use a 30-kW, short pulse CO2 laser focused on a 30 µm liquid tin droplet, repeatedly 50,000 times per second, to produce 250 W of EUV light at a 13.5 nm wavelength. The … Continue reading
