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
CNI Optoelectronics Tech (CNI) offers a nanosecond-pulsed diode laser, with a tunable pulse width of 10 ns to 10 ms (external trigger), good beam profile, and high power stability. Each model of this laser has single wavelength from 375 to 1310 nm. This laser has an ultra-compact design that can be easily integrated into the … Continue reading
CNI Optoelectronics (CNI) introduces the photoelectric-integrated MDL-XL laser series. The features are designed to ensure easy integration, high reliability, adjustable focus, good environmental adaptability, and more. The user simply needs to provide a digital modulation signal to synchronize the enable time and disable time of the laser emission. The MDL-XL series module provides stable performance … Continue reading
Superlum Diodes has launched a new product: the OEM Broadsweepers at 790 nm, 840 nm and 930 nm. These compact, wavelength-swept, tunable lasers are designed to work in OEM applications. They have a maximum sweep rate up to 10000 nm/s and optical power up to 3 mW (up to 20 mW after boosting). Their tuning … Continue reading
Positive GDD compensation in wavelength-tunable optical parametric oscillators (OPOs) exploit the negative nonlinearities for the first time. The results pave the way for a compact and stable femtosecond source for multiphoton imaging applications. Prof. Mikas Vengris, and Ignas Stasevičius at Light Conversion have recently published a paper entitled “Exploiting optical nonlinearities for group delay dispersion … Continue reading
Now the CARBIDE CB3 laser available from Light Conversion has an option for tunable GHz and MHz burst with burst-in-burst capability — called BiBurst. The distance between burst packet groups is called the nanosecond burst (N). The picosecond burst (P) is the distance between sub-pulses in the group. The image below illustrates the difference between the single pulse mode and … Continue reading
