  • Light Conversion TOPAS Prime: Collinear Optical Parametric Amplifier

    topas prime

    Light Conversion TOPAS‑Prime is a two stage femtosecond optical parametric amplifier of white-light continuum. Two product lines of TOPAS‑Prime are available: a "standard energy" line with input energy of up to 3.5 mJ @ 35 fs (up to 4 mJ @ 100 fs) and TOPAS‑Prime‑Plus with increased input energy acceptance of up to 5 mJ @ 35 – 100 fs.

  • Light Conversion HE-TOPAS Prime: High Energy Optical Parametric Amplifier

    he topas

    Light Conversion's HE‑TOPAS‑Prime is a 3‑stage femtosecond optical parametric amplifier of white-light continuum. It is a TOPAS‑Prime with additional high energy and low dispersion amplification stage which allows using up to 60 mJ of pump energy (or even more for custom solutions) and maintaining the shortest possible pulses at the output. Two product lines of HE‑TOPAS‑Prime are available: a "standard energy" line with input energy of up to 8 mJ @35 fs (up to 20 mJ @100 fs) and HE‑TOPAS‑Prime‑Plus with increased input energy acceptance of up to  18 mJ @ 35 fs (up to 47 mJ @ 100 fs). 60 mJ input energy is possible with longer input pulse of ~150 fs.

    Both product lines come with wavelength extension options, which can cover the maximum wavelength range from 189 nm to 20 μm for HE‑TOPAS‑Prime and 240 nm to 20 μm for HE‑TOPAS‑Prime‑Plus.

    We also offer a HE‑TOPAS‑800‑ps model for picosecond pump pulses.

  • Light Conversion TOPAS Twins: Two Independently Tunable Optical Parametric Amplifiers

    topas twins

     

    Light Conversion's TOPAS‑Twins are two independently tunable optical parametric amplifiers (OPAs) integrated into single housing. Both OPAs share the same white light source to provide excellent and bound up stability of both outputs. Shared white light enables the user to generate CEP locked mid‑IR pulses in 4.5 – 15 μm range.

    The maximum pump energy into each OPA depends on the pulse duration; see the specifications for more details. Both OPAs come with wavelength extension options, which can cover the wavelength range from 240 nm to 20 μm. Output specifications for each OPA are the same as of TOPAS‑Prime.

  • Light Conversion SHBC-TOPAS-400-WL Narrow Bandwidth Optical Parametric Amplifier

    shbc topas 400

    Light Conversion's Second Harmonic Bandwidth Compressor (SHBC)-TOPAS-400-WL system is a nonlinear optics device devoted for generation of a narrow bandwidth (3 – 20 cm-1) continuously wavelength tunable pulse when pumped by a femtosecond pulse with bandwidth of 150 – 500 cm-1.

    The device is pumped by a fundamental harmonic of a femtosecond Ti:sapphire laser amplifier and continuously covers wavelength range from 480 to 2400 nm. With optional frequency mixers this range can be extended down to 240 nm and up to 10 microns.

  • Light Conversion TOPAS-White: Non-Collinear Optical Parametric Amplifier

    topas white

    Light Conversion's TOPAS-white is a high energy two amplification stage non – collinear OPA (NOPA) with built in pulse compressor. A non – collinear pumping scheme of an OPA is used when the collinear approach reaches its limits in respect to broad spectral bandwidth and/or extremely short pulses (< 20 fs). The basic principle of operation of NOPA relies on parametric amplification of chirped signal produced by supercontinuum (white-light) generation. The non-collinear geometry is used due to broad amplification bandwidth in the visible spectral range.

    TOPAS-white has a unique optical setup, which allows pumping the device with more than 200 μJ of energy and achieving more than 60 μJ of output at 550 nm.
