Several options further extend the scope of the scientific series of the FemtoFiber lasers. Ultrafast optics is the part of optics dealing with ultrafast phenomena, i. The prototype opto-microfluidic devices and systems provide possibilities to achieve real-time optical measurement, chemical analysis, and biomedical diagnostics. , "Multimodal Coherent Anti-Stokes Raman Pectroscopic Imaging with a Fiber Optical Parametric Oscillator," Applied Physics Letters 98, 191106 (2011). Here, we report on femtosecond (fs) laser microfabrication in special glasses and polymers. The femtosecond laser provided an optical comb for which all the modes were collectively locked to a standard-frequency Rb clock. It is a maskless technology that allows rapid device prototyping, has intrinsic three-dimensional capabilities and can produce both photonic and. 2019 TiF-100ST-F6 femtosecond Ti:S oscillator with Frep locking for multiphoton microscopy at CANDLE, Armenia. A pump-and-probe experiment is implemented in a collinear arrangement, utilizing a time-delayed frequency-doubled probe beam for in situ reflectance measurement and ultrafast microscopy observation. Leemans, supervisor). View program details for SPIE LASE conference on Frontiers in Ultrafast Optics: Biomedical, Scientific, and Industrial Applications XX. The main research fields are information photonics, optical metrology, and laser material processing. Laser Quantum is dedicated to supplying robust and reliable lasers to you. Our designs address these issues by using a single laser cavity to generate both the probe and the local oscillator. Femtosecond Mirrors Broadband, high reflectivity, high laser damage threshold mirrors designed with low and controlled group delay dispersion characteristics specifically for ultrashort laser applications.

Workshop of Photonics (UAB Altechna R&D) and UAB MGF Light Conversion has started a new joint project called „ Creation of the optical module integrated with the femtosecond laser to be used in the laser micromachining workstation (FEMTOMODULIS)“. Note: Citations are based on reference standards. In another, opto-optical modulation was used to redirect XUV emission at a time controlled by the experimenter, with femtosecond precision. LASER VISION was the first private LASIK center in Thailand to acquire the Femtosecond Laser, for the latest and safest in vision correction technology. When femtosecond lasers for cataract surgery were first introduced in the United States, their ability to make accurate astigmatic keratotomy or limbal relaxing incisions was front and center, mainly because that was the only way surgeons could charge for the use of the devices. These femtosecond lasers are combined with an imaging system called optical coherence tomography (OCT). Optical parametric amplifiers have emerged as a powerful tool for generating broadband few-cycle light pulses and are currently the only method to create such pulses at the multi-mJ level. Professor Chunlei Guo. In a femtosecond laser ablation those structures are produced with an very short laser pulses that enables precise controlled way to modify the surface topology. Femtosecond lasers are capable of emitting extremely short optical pulses with time durations all the way down to the femtosecond (10 -5) level. Microfabrication with Femtosecond Laser Processing – (A) Laser Ablation of Ferrous Alloys, (B) Direct-Write Embedded Optical Waveguides and Integrated Optics in Bulk Glasses Pin Yang and George R. Generally, nanosecond lasers offer an economical, higher-throughput solution, whereas picosecond and femtosecond lasers provide high-quality machining of thin, transparent materials. A method for inscribing a waveguide into a glass substrate, the method comprising: relatively moving a femtosecond laser beam along a surface of the glass substrate while maintaining the focus of the laser beam at a given depth from the surface, wherein the glass substrate is a toughened glass. The people at LightMachinery are veterans of the laser and optics world with many years of experience in the areas of optical design, high power lasers, optical fabrication, laser systems, metrology, thin film coatings and custom machinery fabrication. These also exist in ultrafast versions which are ideal for femtosecond pulsed lasers. EKSMA Optics uses cookies to give you the best shopping experience. Read "3-Dimensional simulation and footprint of optical breakdown in dielectrics induced by femtosecond laser pulse, Optics & Laser Technology" on DeepDyve, the largest online rental service for scholarly research with thousands of academic publications available at your fingertips. ) Abbott Medical Optics, Inc. The laser used was a Ti:Sapphire CPA femtosecond laser with λ=775nm, t pulse<150fs, P=0. The laser sources and high speed cameras fit on a small optical bench and need to be carefully calibrated for triggering. Along with the rapid development pace of ultrafast lasers, ultrafast laser optics must overcome the unusually amplified obstacles of dispersion, color aberrations, and ghost reflections through careful design and manufacture. Optics & Laser Components ALPHALAS GmbH offers various op-tical and laser components, polar-ization optics, laser and nonlinear crystals. This contact lens includes a circumferential suction skirt, as in femtosecond refractive laser systems.
