Simultaneous Spatial and Temporal Focusing (SSTF)

[January 21, 2021]
We show how to simulate SSTF Setups in VirtualLab Fusion and invesitgate their characteristics. These setups have the adventage that energy is concentrated in an single spot in space and time domain which reduces detrimental effects and increases precision.

For applications in the area of ultrashort pulse laser technologies, where the properties of the field must be controlled in both the space and time domains, “Simultaneous Spatial and Temporal Focusing” (SSTF) is a frequently used technique. Such setups often lead to spatiotemporal effects like the pulse front tilt. We built a commonly used SSTF setup to investigate the spatiotemporal behavior of the field in the focus and the effects of various system parameters on the resulting pulse front tilt.

Save your Seat for Our First User Meetup on Gratings

[January 18, 2021]
Due to the current situation, exhibitions and on-site events are unfortunately not possible. Nevertheless, we would like to create an opportunity for talking virtually with our optical engineers and sales representatives about current projects and developments. Therefore, we launched a new event format called User Meetup. To inaugurate this new format we have chosen the topic of gratings.

Tight Focusing for Immersion Microscopy and STED Microscopy

[January 14, 2021]
We demonstrate that the asymmetric PSF is further elongated behind the coverslip. Moreover, STED (stimulated emission depletion) microscopy, which is widely used for tens-of-nanometer resolution, requires a donut-shaped PSF for depletion.

We demonstrate that the asymmetric PSF is further elongated behind the coverslip. Moreover, STED (stimulated emission depletion) microscopy, which is widely used for tens-of-nanometer resolution, requires a donut-shaped PSF for depletion.

Tight focusing by high-NA objective lenses, which generates a small PSF (Point Spread Function), is essential for high-resolution microscopy systems. Among many other microscopy systems, immersion microscopy uses a coverslip to separate the immersion liquid and the specimen. It may distort the PSF at the focal plane. We demonstrate that the asymmetric PSF is further elongated behind the coverslip.  Moreover, STED (stimulated emission depletion) microscopy, which is widely used for tens-of-nanometer resolution, requires a donut-shaped PSF for depletion. We follow the proposed method by P. Török and P.R.T Monro to model the tight focusing of a Gaussian-Laguerre beam. The generation of a donut-shaped PSF is demonstrated.
