The PHAROS is a femtosecond laser system combining millijoule pulse energies and high average powers. PHAROS features a mechanical and optical design optimized for industrial applications such as precise material processing. Compact size, integrated thermal stabilization system and sealed design allow PHAROS integration into machining workstations. The use of solid state laser diodes for pumping of Yb medium significantly reduces maintenance cost and provides long laser lifetime.

Tunable PHAROS parameters include: pulse duration (190 fs – 20 ps), repetition rate (single pulse to 1 MHz), pulse energy (up to 2 mJ) and average power (up to 20 W). Its deliverable power is sufficient for most of material processing applications at high machining speeds. The built-in pulse picker allows convenient control of the laser output in pulse on demand mode. The compact and robust optomechanical design features of PHAROS lead to stable laser operation in varying environments.

The PHAROS laser can be equipped with automated harmonics modules. A selection of fundamental (1030 nm), second (515 nm), third (343 nm), fourth (257 nm) or fifth (206 nm) harmonic outputs are available through software control.

Harmonics generators are designed to be used in industrial applications where a single output wavelength is desired. Modules are mounted directly on the output of the laser and integrated into the system.

PHAROS has an option for tunable GHz and MHz burst with burst-in-burst capability – called BiBurst. The distance between burst packet groups is called nanosecond burst, N (MHz-Burst). The distance between sub-pulses in the group is called picosecond burst, P (GHz-Burst). In single pulse mode, one pulse is emitted at a time at some fixed frequency. In burst mode, the output consists of several picosecond burst packets each separated by an equal time period between each packet. Each packet can contain a number of sub-pulses which are also separated by an equal time period between each pulse.

High pulse energy femtosecond laser with 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.

BiBurst material fabrication areas cover:

- brittle material drilling and cutting

- deep engraving

- selective ablation

- transparent materials volume modification

- hidden marking

- surface functional structuring

The femtosecond Yb oscillator FLINT is based on an Yb-doped crystal pumped with a high brightness laser diode module. Generation of femtosecond pulses is achieved by Kerr lens mode-locking. Once started, mode-locking remains stable over a long period of time and is immune to minor mechanical impact. A piezo-actuator can be included in customized oscillators in order to control the cavity length. The FLINT oscillator can also be equipped with a carrier envelope phase (CEP) stabilization system.

FEATURES:

- sub-40 fs without any additional pulse compressor

- 250 nJ pulse energy

- 20 W output power

- 76 MHz is standard

- no amplified spontaneous emission

- rugged, industrial-grade mechanical design

- automated harmonic generator (517 nm)

- optional CEP stabilization

- possibility to lock to external clock

Optical parametric amplifiers made by Light Conversion set the industry standard for more than 25 years. The TOPAS series devices pumped with Ti:sapphire lasers and ORPHEUS series pumped by ytterbium-based solid-state or fiber lasers are capable of producing 190 nm to 20 µm tunable wavelength output, are reliable and simple to use, while still flexible for custom and most demanding applications. Input and output parameters can be chosen in the widest range possible in the market. With our standard products, it is possible to combine both – short pulse and narrow bandwidth – in optically synchronized pulses. Light Conversion can deliver complete spectroscopic laser systems with high temporal or spectral resolution using multi-beam setups.

Light Conversion has developed high-energy OPCPA systems, which are pumped with picosecond Nd:YAG lasers. Their attractive features:

- pre-pulse contrast exceeding 10¹²

- sub-220-mrad CEP noise and <1% energy fluctuations maintained throughout the full day of operation

- safe and simple spectral-temporal shaping of output pulses possible

- integrated control and diagnostics system

- less than 1 hour warm-up time

The CARBIDE femtosecond lasers feature an output power of >80 W at 1030 nm wavelength. The laser emits pure pulses with ASE background of <10⁻⁹ and recently updated maximum energy specifications without compromises to the beam quality, industrial grade reliability and beam stability regardless of environmental conditions. Continuously tunable repetition rate in a range of 60 kHz to 2 MHz is combined with an in-built Pulse Picker for output pulse timing and full-scale energy control with <10 microsecond response time, enabling arbitrary shaping of the emission. Pulse duration can be tuned in a range of 290 fs – 10 ps. Excellent power stability of <0.5% RMS is standard. The laser output can be split into a burst of several pulses of pico- and nano- separation while having the ability to modify the burst envelope. Harmonic generator options permit femtosecond applications at different wavelengths. The parameters are entirely software adjustable.

The scientific interface module for CARBIDE features:

- uncompressed laser output access

- provides simultaneous OSC output ( 65 MHz, <100 fs, >100 mW output power)

- beam-splitting options

The HARPIA comprehensive spectroscopy system performs a variety of sophisticated time-resolved spectroscopy measurements in a compact footprint. It also offers an intuitive user experience and easy day-to-day maintenance meeting the needs of today's scientific applications. Despite its small size, the HARPIA system is easily customizable and can be tailored to specific measurement needs. The system is configured around the HARPIA-TA transient absorption spectrometer and can be expanded using time-correlated single-photon counting and fluorescence upconversion (HARPIA-TF), third beam delivery (HARPIA-TB) and microscopy modules. Switching between different measurement modes is mostly automated and requires very little user interaction. Adhering to the standards set by the ORPHEUS product line, each module is contained in a single monolithic aluminium body ensuring excellent optical stability and minimal optical path lengths.

For a robust and versatile single-supplier solution the HARPIA spectroscopy system can be combined with a PHAROS or a CARBIDE laser together with ORPHEUS series OPAs. HARPIA also supports Ti:sapphire lasers with TOPAS series OPAs.
