Light Conversion‘s femtosecond wavelength-tunable sources are based on optical parametric amplification technology. Recent advancements in Yb-based ultrafast optical parametric amplifiers (OPAs) have expanded tuning ranges from deep-UV to mid-IR, reduced pulse durations, and enabled high-contrast pulses, and high output stability. These compact, hands-off solutions are now easier to integrate into life sciences research, enabling multidimensional studies of dynamic processes.

Light Conversion’s OPAs are built on three distinct platforms to meet specific application needs:

• ORPHEUS: A classic OPA platform that many users are familiar with – simple to use yet offering an extensive range of parameters.
• ORPHEUS-NEO: A next-generation OPA equipped with multiple detectors for continuous power monitoring and diagnostics.
• I-OPA: A compact OPA integrated directly onto the laser, undergoing vibrational and thermal testing – the only commercial industrial-grade OPA.

When paired with PHAROS or CARBIDE femtosecond lasers, our OPAs serve as an invaluable resource for ultrafast spectroscopy, nonlinear microscopy, and a wide range of other scientific applications. Since the early 1990s, Light Conversion’s OPAs have been synonymous with ultrafast spectroscopy and applications ranging from multiphoton imaging and optogenetic stimulation in neuroscience to wavelength-selective micromachining. Today, they continue to dominate the market, supplying approximately 95% of the global demand for optical parametric amplifiers.

Refer to the tables below for detailed platform specifications and a selection guide to help you choose your next wavelength-tunable source based on the desired pulse duration and spectral range.
