Light Conversion Orpheus: Collinear Optical Parametric Amplifier

Light Conversion's ORPHEUS is a collinear optical parametric amplifier of white‑light continuum pumped by femtosecond Ytterbium based laser amplifiers. With the additional feature of being able to work at high repetition rates, ORPHEUS maintains the best properties of TOPAS series amplifiers: high output pulse stability throughout the entire tuning range, high output beam quality and full computer control via USB port as well as optional frequency mixers to extend the tuning range from UV up to mid‑IR ranges.
Light Conversion Orpheus-HP: High Power Collinear Optical Parametric Amplifier

Light Conversion's ORPHEUS‑HP is a collinear optical parametric amplifier of white‑light continuum pumped by PHAROS laser. The device is a modified version of the ORPHEUS, with UV‑VIS tuning range frequency mixers integrated into a thermally‑stabilized monolithic housing. ORPHEUS‑HP also provides the option of generating deep ultraviolet pulses (190 nm – 215 nm), in addition to 210 nm – 2600 nm.

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 nm – 5000 nm).
Light Conversion Orpheus-One: Mid-IR Collinear Optical Parametric Amplifier

Light Conversion's ORPHEUS‑ONE is a collinear optical parametric amplifier of white‑light continuum pumped by femtosecond Ytterbium based laser amplifiers and focused on mid‑infrared wavelengths generation in two stages.

In comparison to standard ORPHEUS + DFG configuration, the ORPHEUS‑ONE provides higher conversion efficiency into the infrared range.
Light Conversion Orpheus-N: Non-Collinear Optical Parametric Amplifier

Light Conversion's 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 nm – 850 nm range with average power of more than 0.5 W at 700 nm*. ORPHEUS‑N with third harmonic pump (ORPHEUS‑N‑3H) delivers pulses of less than 30 fs in 530 nm – 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.
Light Conversion ORPHEUS Twins: Two Independently Tunable Optical Parametric Amplifiers

Light Conversion's ORPHEUS‑Twins – two independently tunable optical parametric amplifiers designed for flexible pump parameters and OPA configuration. The two channels can be separately configured to be a version of either ORPHEUS, ORPHEUS‑ONE or ORPHEUS‑F.

Both OPA units are integrated into a single housing and share the same white light seed for amplification. The design of this OPA enables hands free wavelength tuning, optional automated wavelength separation and the possibility of generating broad band mid-infrared radiation, in the region of 4 µm – 16 µm, with a passively stable Carrier Envelope Phase (CEP).
Light Conversion Orpheus-PS :Narrow Bandwidth Optical Parametric Amplifier

Light Conversion's ORPHEUS‑PS is a narrow bandwidth optical parametric amplifier of white light continuum designed for PHAROS pump laser. This device is pumped by the picosecond pulses produced in SHBC‑515 narrow bandwidth second harmonic generator and seeded by white light continuum generated by femtosecond pulses. This enables to achieve very high pulse to pulse stability compared to other methods of generating tunable picosecond pulses. The white light generation module is also integrated into the same housing as amplification modules enabling even better long term stability and ease of use. The system features high conversion efficiency, nearly bandwidth and diffraction limited output, full computer control via USB port and LabVIEW drivers.
Light Conversion I-OPA for PHAROS: Optical Parametric Amplifier I-OPA, Industrial grade

Light Conversion's I‑OPA is an optical parametric amplifier of white‑light continuum pumped by the PHAROS laser. This OPA is focused on generating long‑term stable output with reliable and hands‑free operation. Manually tunable output wavelength extends the application possibilities of a single laser source instead of requiring multiple lasers based on different technologies.
Light Conversion Orpheus-F: Broad Bandwidth Hybrid Optical Parametric Amplifier

Light Conversion's 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 < 60 fs in most of the tuning range, while Idler is compressed in bulk material down to 40 fs – 90 fs depending on wavelength.

It is possible to limit the output bandwidth to some extent (up to 2 – 3 times) without losing any output power. By comparison, standard ORPHEUS device uses spectral narrowing to produce bandwidth‑limited 200 fs – 300 fs duration pulses directly at the output, with extended Signal/Idler tuning range and options to generate ultraviolet and mid‑infrared light. Our non‑collinear ORPHEUS‑N‑2H device produces even broader bandwidths, compressible down to 20 fs, but limits the tuning range to 650 nm – 900 nm. This places the performance of ORPHEUS‑F configuration in between our other solutions.
