Light Conversion's Ultrafast Laser Solutions Illuminate Scientific Frontiers

Posted  by GoPhotonics


Light Conversion, a pioneer in femtosecond optical parametric amplifiers (OPAs) and Yb-based femtosecond laser sources, emerged as one of the world’s leading manufacturers of femtosecond lasers. It was founded in 1994 with roots at the Vilnius University Laser Research Center.

With proven competence in laser design and manufacturing, state-of-the-art R&D facilities, and close ties to research programs, Light Conversion offers unique solutions for today’s industrial, scientific, and medical challenges. The reliability of our femtosecond lasers has been proven by hundreds of systems operating 24/7 for more than 10 years in the industrial market. Using our knowledge, experience, and highly motivated professional team, we focus on quality and customer satisfaction.

The product portfolio is all about ultrafast and ultraprecise. To satisfy industrial and scientific needs, we must be reliable and productive, but at the same time, flexible and versatile. Our goal is to maintain the right balance to satisfy the most demanding customers from various markets.

Femtosecond Lasers

Light Conversion has worldwide recognition for its industrial-grade Yb-based PHAROS, CARBIDE, and FLINT femtosecond lasers. The PHAROS series focuses on customizability, reliability, and process-tailored output parameters, providing down to 100 fs pulse duration and up to 4 mJ pulse energy. The CARBIDE series provides a compact industrial design with air- and water-cooled models, the latter reaching 120 W output power and 2 mJ pulse energy while sustaining excellent output stability. The FLINT oscillators extend the parameter range with repetition rate from 10 to 100 MHz. All together cover a wide range of scientific, industrial, and medical applications.

Harmonic Generators

PHAROS and CARBIDE lasers, as well as FLINT oscillators, can be equipped with modules for a high-efficiency harmonic generation. This includes industrial-grade harmonic generators (HGs), automated and fully integrated into the system, and HIRO, a free-standing module offering simultaneous outputs, thus more fitting to scientific applications. Furthermore, the selection includes econd harmonic bandwidth compressors (SHBC), dedicated to the conversion of narrow-bandwidth picosecond pulses from the broadband output of femtosecond lasers.

Automated and customizable harmonic generators are also available.

Wavelength-Tunable Sources for Yb Lasers

The femtosecond wavelength-tunable sources are based on optical parametric amplification technology. Optical parametric amplifiers (OPAs) for Yb lasers enable operation at high repetition rates while maintaining the best properties of TOPAS series OPAs such as the wide tuning range from deep-UV to mid-IR and high output stability. Our OPAs are built in three different platforms to suit your specific needs:

  • ORPHEUS represents the classic OPAs that many are used to. Just like TOPAS, it is quite simple yet offers an extensive range of parameters.
  • ORPHEUS-NEO introduces the next generation of OPAs equipped with multiple detectors for continuous power monitoring and diagnostics.
  • I-OPA is a compact OPA integrated on the laser and undergoes vibrational and thermal testing, making it the only commercial industrial-grade OPA.

Coupled with PHAROS or CARBIDE femtosecond laser, our OPAs make an invaluable source for ultrafast spectroscopy, nonlinear microscopy, and a variety of other scientific applications. See the tables below for more details on the platforms, as well as selection guide for your next wavelength-tunable source based on the desired pulse duration and spectral range.

Wavelength-Tunable Sources for Ti:Sapphire Lasers

TOPAS is a series of femtosecond optical parametric amplifiers (OPAs) for Ti:Sapphire lasers which delivers continuous wavelength tunability from 189 nm to 20 μm, high conversion efficiency, high output stability, and full computer control. With more than 2000 units installed worldwide, TOPAS has become an OPA market leader for numerous scientific applications. TOPAS can be pumped by Ti:Sapphire lasers with pulse duration from 20 fs to 200 fs and pulse energy from 15 μJ to 60 mJ.

Optical Parametric Chirped-Pulse Amplification Systems

Optical parametric chirped-pulse amplification (OPCPA) is the only currently available laser technology that simultaneously provides high peak and average power and few-cycle pulse duration required by the most demanding scientific applications. Our portfolio of cutting-edge OPCPA products is based on years of experience developing and manufacturing optical parametric amplifiers and femtosecond lasers. The few-cycle CEP-stable pulses come either in a compact table-top ORPHEUS-OPCPA or a large but TW-level OPCPA-HE, similar to SYLOS at ELI ALPS.

Ultrafast Spectroscopy Systems

The HARPIA ultrafast spectroscopy system performs a variety of sophisticated time-resolved spectroscopic measurements in a compact footprint. It offers an intuitive user experience and easy day-to-day maintenance, meeting the needs of today’s scientific applications.

The HARPIA-TA is a transient absorption spectroscopy system. Extension modules and customization options tailor the HARPIA system to specific measurement needs. In particular, it can be expanded using time-correlated single-photon counting and fluorescence upconversion (HARPIA-TF), third beam delivery (HARPIA-TB), and microscopy (HARPIA-MM) modules. HARPIA is designed for easy switching between measurement modes and comes with dedicated data acquisition and analysis software. Each module is contained in a monolithic aluminum body, ensuring excellent optical stability and minimal optical path lengths.

The HARPIA-TG is a novel transient grating spectroscopy system dedicated to the measurement of the diffusion coefficient and carrier lifetime. The fully automated and computer-controlled system enables the measurement in a matter of minutes.

Laser Sources for Nonlinear Microscopy

Light Conversion product portfolio with recently released microscopy-dedicated femtosecond laser sources, CRONUS-2P and CRONUS-3P, covers applications in functional neuroimaging, optogenetics, and deep imaging using medium-repetition-rate three-photon excitation and fast high-repetition-rate two-photon imaging, as well as widefield and holographic excitation using high-power laser sources. See the CRONUS series comparison table below, while the complete list of laser sources for nonlinear microscopy and examples of the state-of-the-art applications are available in our latest brochure.

With a strong emphasis on quality, customer satisfaction, and a highly skilled team, Light Conversion continues to push the boundaries of femtosecond laser technology, contributing to advancements in various scientific disciplines. Their dedication to research, development, and innovation positions them as a key player in the global laser technology landscape. As Light Conversion looks towards the future, it remains well-positioned to meet the evolving needs of industries and researchers worldwide.
