Light Conversion

The GECO and TIPA autocorrelators are designed for ultrashort pulse duration measurements in a 500 – 2000 nm spectral range. GECO is the preferred solution for daily measurements of medium- and high-repetition-rate laser systems, measuring pulse durations between 10 fs and 20 ps, intuitive use, and capability of FROG trace measurements. TIPA is explicitly designed for low-repetition-rate laser systems, enabling single-shot measurements and pulse-front tilt analysis.

LIGHT CONVERSION has worldwide recognition for its industrial-grade Yb-based PHAROS and CARBIDE femtosecond lasers and FLINT femtosecond oscillators. The PHAROS series focuses on customizability, reliability, and process-tailored laser output parameters. The CARBIDE series provides a compact industrial-grade design with air- and water-cooled models, the latter reaching output power of up to 80 W. The FLINT oscillators extend the parameters range with a 76 MHz repetition rate. Thus, all together cover a wide range of scientific, industrial, and medical applications.

Optical parametric chirped-pulse amplification (OPCPA) is the only currently available laser technology simultaneously providing high peak and average power, as well as few-cycle pulse duration required by the most demanding scientific applications. Our answer to these demands is a portfolio of cutting-edge OPCPA products based on years of experience in developing and manufacturing optical parametric amplifiers and femtosecond lasers. With a peak power up to >5 TW, pulse durations down to 6.5 fs and CEP stability of <250 mrad, it is an excellent laser source for high harmonic generation.

The CARBIDE is a series of femtosecond lasers combining high average power and excellent power stability. CARBIDE features market-leading output parameters without compromises to beam quality and stability. The compact and robust optomechanical CARBIDE design allows a variety of applications in top-class research centers, as well as display, automotive, LED, medical, and other industries. The reliability of CARBIDE has been proven by hundreds of systems operating 24/7 in the industrial environment.

The tunability of CARBIDE lasers enables our customers to discover the most efficient manufacturing processes. Tunable parameters include pulse duration (190 fs – 20 ps), repetition rate (single-shot – 2 MHz), pulse energy (up to 0.8 mJ), and average power (up to 80 W). A pulse-on-demand mode is available using the built-in pulse picker. The CARBIDE lasers can be equipped with industrial-grade modules.

The FLINT oscillators are based on an Yb-doped crystal pumped with high brightness laser diodes. The generation of femtosecond pulses is achieved with Kerr lens mode-locking. Once started, mode-locking remains stable over a long period and is immune to minor mechanical impact. The oscillator cavity length can be adjusted using an optional piezo actuator. The FLINT oscillators can also be equipped with carrier–envelope phase (CEP) stabilization and repetition rate locking to an external source.

The industrial-grade femtosecond PHAROS and CARBIDE lasers have an option for tunable GHz and MHz burst with burst-in-burst capability – called BiBurst. In standard mode, a single pulse is emitted at some fixed frequency. In burst mode, the output consists of pulse packets instead of single pulses. Each packet consists of a certain number of equally separated pulses. A MHz burst contains N pulses with a nanosecond period, while a GHz burst contains P pulses with a picosecond period. If both bursts are used, the equally separated pulse packets contain sub-packets of pulses (burst-in-burst, BiBurst).

The high pulse energy femtosecond laser with the flexible BiBurst functionality brings new production capabilities to high-tech manufacturing industries such as consumer electronics, integrated photonic chip manufacturing, stent cutting, surface functionalization, future displays manufacturing, and quantum computing.

The ORPHEUS-MIR is an optical parametric amplifier (OPA) optimized for the efficient generation of broad-bandwidth mid-IR pulses. The system provides broadband pulses in the tuning range of 2.5 – 10 μm and reaches up to 15 μm with an optional narrow-bandwidth extension. Due to the novel system design, ORPHEUS-MIR provides < 100 fs pulses directly at the output. Signal and idler outputs are available simultaneously. The system architecture is well suited for pumping with the high-energy and high-power PHAROS and CARBIDE lasers.

The highlight of tunable wavelength sources is the ORPHEUS series of femtosecond optical parametric amplifiers (OPAs) for pumping with Yb-doped lasers. The ORPHEUS series enables 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. In combination with the PHAROS or CARBIDE femtosecond laser, it makes an invaluable source for ultrafast spectroscopy, nonlinear microscopy, and a variety of other applications. The list of tunable wavelength sources has been recently extended by the addition of I-OPA, a compact industrial-grade OPA, and CRONUS-3P, an OPA-based ultrafast source with GDD control for advanced nonlinear microscopy.

The PHAROS is a series of femtosecond lasers combining millijoule pulse energy and high average power. The PHAROS features a mechanical and optical design optimized for both scientific and industrial applications. A compact, thermally-stabilized, and sealed design enables the integration of PHAROS into various optical setups and machining workstations. The diode-pumped Yb laser medium significantly reduces maintenance costs and provides a long laser lifetime, while the robust optomechanical design enables stable operation in varying environments.

The tunability of PHAROS allows the system to cover applications normally requiring multiple different laser systems. Tunable parameters include pulse duration (190 fs – 20 ps), repetition rate (single-shot – 1 MHz), pulse energy (up to 2 mJ), and average power (up to 20 W). A pulse-on-demand mode is available using the built-in pulse picker. The versatility of PHAROS can be extended by a variety of optional modules.
