📏 𝗖𝗵𝗮𝗿𝗮𝗰𝘁𝗲𝗿𝗶𝘇𝗶𝗻𝗴 beam shapes made simple 📐   💢 Our laser beam diagnostic solutions are able to record nearly any beam shape. 💢   But 𝗺𝗲𝗮𝘀𝘂𝗿𝗶𝗻𝗴 is much more than that.   Measurement is the assignment of a number to a characteristic of an object or event, which can be compared with other objects. Even if fixed definitions are not available for all laser characteristics, our LDS will provide a result relevant to your measurement task.   Would you like to evaluate a non-circular beam, simply contact one of our #experts! 📲 support@primes.de #innovation #technology #future #energy #research #software #Primes #beamdiagnostics #laser

The Types Of Electro-Optic Modulators Are Briefly Described An electro-optical modulator (EOM) controls the power, phase and polarization of a laser beam by electronically controlling the signal. The simplest electro-optic modulator is a phase modulator consisting of only one Pockels box, where an electric field (applied to the crystal by an electrode) changes the phase delay of the laser beam after it enters the crystal. The polarization state of the incident beam usually needs to be parallel to one of the optical axes of the crystal so that the polarization state of the beam does not change. In some cases only very small phase modulation (periodic or aperiodic) is required. For example, EOM is commonly used to control and stabilize the resonant frequency of optical resonators. Resonance modulators are usually used in situations where periodic modulation is required, and a large modulation depth can be obtained with only a moderate driving voltage. Sometimes the modulation depth is very large, and many sidelobe (light comb generator, light comb) are produced in the spectrum. Polarization modulator Depending on the type and direction of the nonlinear crystal, as well as the direction of the actual electric field, the phase delay is also related to the polarization direction. Therefore, the Pockels box can see multi-voltage controlled wave plates, and it can also be used to modulate polarization states. For linearly polarized input light (usually at an Angle of 45° from the crystal axis), the polarization of the output beam is usually elliptic, rather than simply rotated by an Angle from the original linearly polarized light. Amplitude modulator When combined with other optical elements, especially with polarizers, Pockels boxes can be used for other kinds of modulation. The amplitude modulator in Figure 2 uses a Pockels box to change the polarization state, and then uses a polarizer to convert the change in polarization state into a change in the amplitude and power of the transmitted light. #Optical #photonics #semiconductor #Optics #opticalcenter #SiliconPhotonics #photodetectors #optomechanics #laser Read more: https://lnkd.in/gd6sEShT

📣 Register now for our upcoming Laserlab-Europe Talk: "Radiation sources based on #laser #plasma interaction and applications in #materialsscience" by Teresa Cebriano Ramírez (CLPU. CENTRO DE LÁSERES PULSADOS, Spain) 📅 17 April 2024, 4:00pm CEST 📌 Register now: https://lnkd.in/eDtTtHg6 🎬 Watch all previous Laserlab-Europe Talks on our YouTube channel: https://lnkd.in/eHTvBdiw 💡 The CLPU operates VEGA, a multi Terawatt laser system composed by three independent and synchronized 30 fs long pulses: VEGA-3 of 1 PW (at 1Hz), VEGA- 2 of 200 TW and VEGA-1 of 20 TW (both up to 10 Hz). The interaction of these pulses with matter (in solid, liquid or gaseous states) generates different plasma states and in turn, the emission of different particle beams with different energy ranges. These are protons (few keV up to 20 MeV) and ion sources, electrons (up to 500 MeV), neutrons, X-rays and gamma rays. All these sources provide a direct application in the field of materials characterization and synthesis such as PIXE (particle induced X-ray emission), PIGE (particle induced gamma ray emission), EDX, imaging, X-ray fluorescence, lithography (p-writing) or ion implantation. In addition, radiation hardness tests of materials and devices can be performed with direct laser irradiation (damage threshold). Furthermore, the experimental conditions of laser-plasma interaction resemble those of space and planetary ambient which makes them valid for equipment and electronics commissioning for space missions. Finally, the CLPU provides also a laser micro processing station, possibility of nanoparticle production, interaction with biological tissues and microsurgery, fabrication of photonic elements, etc. The Centre also has all the required resources to set up different spectroscopical analysis techniques as tools for control and diagnose in situ the micro processing as Laser induced Breakdown Spectroscopy (LIBS).

"A femtosecond laser emits ultra-short optical pulses with durations below one picosecond, reaching the femtosecond domain (1 fs = 10-15 s). Femtosecond lasers are characterized by their extremely short pulse widths and high peak intensities. The ultra-short bursts minimize residual heating, ensuring precise material processing with minimal collateral damage. Their high peak intensities induce nonlinear optical interactions like multiphoton ionization and plasma formation, providing precise spatial control over laser energy for various applications." #photonics #lasers #lithography
