ORPHEUS-HE is a collinear optical parametric amplifier of white light continuum pumped by PHAROS laser. This model is specially adapted for high pulse energy operation to produce the highest quality beam at the output. The OPA is assembled into a monolithic housing with integrated UV, visible and mid-infrared tuning range extensions available as options.
The design of this OPA offers completely hands free operation, ensuring the same position, direction and polarization for
all wavelengths in UV near IR region covering 190 – 2600 nm tuning range. A dedicated output port is available for the mid-infrared wavelength extension, which covers the 2.4 μm to 16 μm range.PHEUS-HE also integrates a mini spectrometer for online monitoring of OPA output wavelength and remote trouble-shooting. Thermally-stabilized housing helps to decrease sensitivity to ambient temperature, maintaining constant output beam pointing and optical path length for long-term measurements. This OPA can also be re-configured to work with lower energy pump pulses at higher repetition rates to exploit the versatility of our PHAROS product line.
PHAROS is a single-unit integrated 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. Most of the PHAROS output parameters can be easily set via PC in seconds.
Tunability of laser output parameters allows PHAROS system to cover applications normally requiring different classes of lasers. Tunable 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. PHAROS compact and robust optomechanical design features stable laser operation across varying environments. PHAROS is equipped with an extensive software package which ensures smooth hands‑free operation.
CARBIDE industrial femtosecond laser features an output power of > 40 W at 1028 nm wavelength. The laser emits single pure temporal contrast (>1:200) and up to 400 μJ energy pulses without any compromises to the beam quality, industrial grade reliability and beam stability regardless of the environment it is put in. Continuously tunable base repetition rate in a range of 60 – 1000 kHz is combined with an in-built pulse picker for convenient output pulse control. Software adjustable pulse duration can be easily set in a range of 290 fs – 10 ps in seconds. Excellent power stability of < 0.5 % RMS is standard.
Single monolithic housing allows fast warm-up times. Laser is maintenance free. Electronical and most optical components in the laser are field accessible and upgradeable. Carbide ships with an integrated shutter fulfilling performance level d requirements according to EN 13849-1 by default.
Due to an in-built computer laser control is smooth via the provided extensive software package. Multiple custom laser control options are also available; they are convenient when lasers are being integrated in medical or industrial processing applications. CARBIDE can be equipped with a growing number of optional features: a beam expansion unit, an automated attenuator, harmonics or can be used as a seed source for parametric amplifiers and OPCPA systems.
The FLINT oscillator is based on Yb crystal pumped by high brightness laser diode module. Generation of femtosecond pulses is provided by Kerr lens mode-locking. Once started, mode-locking remains stable over a long period of time and is immune to minor mechanical impact. Piezo-actuator can be implemented in customized oscillators in order to control the cavity length. FLINT oscillator can also be equipped with Carrier Envelope Phase (CEP) stabilization system.
ORPHEUS-HP and ORPHEUS-ONE-HP are collinear optical parametric amplifiers of white light continuum pumped by femtosecond Ytterbium based laser amplifiers. The device is a modified version of the ORPHEUS.
ORPHEUS-HP is available with UV VIS tuning range frequency mixers integrated into a thermally stabilized monolithic housing.
Also provides the option of generating deep ultraviolet pulses (190 – 215 nm), in addition to 210 – 2600 nm as well as DFG extension available (tuning range 2200 – 16000 nm). Where ORPHEUS-ONE-HP can provide DFG extension (tuning range 4500 – 16000 nm).
ORPHEUS-HP provides tunable OPA output (630 – 2600 nm). While ORPHEUS-ONE-HP provides tunable OPA output (1350 – 4500 nm).The scheme used in ORPHEUS ONE-HP can generate > 150 cm-1 when OPA is configured for broad bandwidth amplification.
The design of this OPA offers completely hands free wavelength tuning and automatic wavelength separation, also ensuring the same position and direction for all wavelengths in UV near IR region. ORPHEUS HP integrates a mini spectrometer for online monitoring of output wavelength and comes with specialized software that enables wavelength feedback and automatic calibration.
ORPHEUS HP is highly recommended over standard ORPHEUS if the input power is more that 8 W or whenever the necessary tuning range requires both UV and mid infrared generation (for example 315 – 5000 nm). In comparison to standard ORPHEUS-HP + DFG configuration, the ORPHEUS ONE-HP provides higher conversion efficiency into the infrared range.
ORPHEUS-F is a hybrid optical parametric amplifier of white-light continuum pumped by femtosecond Ytterbium based laser amplifiers. This OPA combines the short pulse durations that are produced by a non-collinear OPA and wide wavelength tuning range offered by collinear version. The Signal beam can be easily compressed with a simple prism-based setup down to

ORPHEUS-N is a non-collinear optical parametric amplifier (NOPA) pumped by the PHAROS laser system. Depending on the ORPHEUS-N model, it has a built in second or third harmonic generator producing 515 nm or 343 nm pump. ORPHEUS-N with second harmonic pump (ORPHEUS-N-2H) delivers pulses of less than 30 fs in 700 – 850 nm range with average power of more than 0.5 W at 700 nm 1). ORPHEUS-N with third harmonic pump (ORPHEUS-N-3H) delivers pulses of less than 30 fs in 530 – 670 nm range with average power of more than 0.2 W at 550 nm*. ORPHEUS-N works at repetition rates of up to 1 MHz. The device is equipped with computer controlled stepping motor stages, allowing automatic tuning of the output wavelength. An optional signal’s second harmonic generator is also available, extending the tuning range down to 250 – 450 nm. Featuring a state of the art built in pulse compressor ORPHEUS-N is an invaluable instrument for time-resolved spectroscopy. More than two ORPHEUS-N systems can be pumped with a single PHAROS laser providing several pumpand/or probe channels with independent wavelength tuning.
