The industrial-grade optical parametric amplifier I-OPA series marks a new era of simplicity in the world of tunable wavelength femtosecond light sources. Based on over 10 years of experience producing the ORPHEUS series of optical parametric amplifiers, this solution brings together the tunability of wavelength with the robust industrial-grade design. The I-OPA is a rugged module attachable to our PHAROS and CARBIDE lasers, providing long-term stability comparable to that of the industrial-grade harmonic generators.

The tunable-wavelength I-OPA (I-OPA-TW) provides a wide tuning range and is primarily intended for spectroscopy and microscopy applications. In particular, the -HP model is targeted to be coupled with our HARPIA spectroscopy system as a pump beam source for ultrafast pump-probe spectroscopy. The -F model is primarily designed as a light source for multiphoton microscopy, the -ONE model – for IR spectroscopy and other applications where high energy mid-IR pulses are desired. All of the models can also be used for micromachining and other industrial applications.

The fixed-wavelength I-OPA (I-OPA-FW) is primarily intended for applications that desire a single-wavelength output. The industrial-grade design provides mechanical stability and eliminates the effects of air-turbulence, minimizing energy fluctuations and ensuring stable long-term performance. The I-OPA-TW is best suited for R&D systems, while the I-OPA-FW is a cost-effective solution for large-scale production.

  1. I‑OPA‑TW‑F outputs broad bandwidth pulses which are compressed externally.
  2. Output pulse duration depends on wavelength and pump laser pulse duration. I-OPA-TW-F requires pulse compressors to achieve short pulse duration.
  3. Up to 16 µm tuning range is accessible with external difference frequency generator (DFG).

  1. A single wavelength can be selected from the Signal/Idler range. Signal will have accessible Idler pair, and vice versa.
  2. I-OPA-FW-F outputs broad bandwidth pulses which are compressed externally.
  3. Output pulse duration depends on wavelength and pump laser pulse duration. I-OPA-FW-F requires external pulse compressors to achieve short pulse duration.

  1. Note that the pulse energy scales linearly in a broad range of pump parameters. For example, a PHAROS-PH2-20W laser at 50 kHz (400 μJ energy) will increase the output power twice, and the pulse energy 4 times compared to the reference table above. The pulse duration at the output is < 300 fs in all cases. The OPA output is not limited to these particular ranges of operation, it is continuously tunable as shown in tuning curves.
