** HE-TOPAS stage – additional amplification stage for TOPAS-Prime, TOPAS-Twins or TOPAS-C.

TOPAS-Prime

TOPAS-Prime is our new generation of optical parametrical amplifiers. TOPAS-Prime introduces better mechanical stability and improved sum frequency generation while maintaining all the best parameters of its predecessor – TOPAS-C. TOPAS-Prime is more versatile in terms of input power and beam diameter parameters in comparison with TOPAS-C. Pumped by a fundamental harmonic...

NirUVis

Add-on frequency mixer unit for TOPAS-Prime series devices. A few options available- see Description. The fully automated option has single output port for all wavelengths in 240-2600nm range – same position and direction. It consists of three computer controlled nonlinear crystal stages combined with automated wavelength separator wheels in a monolithic housing. Output is generated by employing a combination of second and fourth harmonic generation as well as sum freq...

HE-TOPAS-Prime

HE-TOPAS-Prime maintains all the best features of “TOPAS” parametric amplifiers. Additionally, input pump energy is accepted up to 60 mJ (or even more for custom solutions). Unmatched dispersion free amplification in additional crystal is added to standard TOPAS-Prime (TOPAS) section in order to accept highest possible pump power (12 mJ 25 fs or 60 mJ 100 fs pulses can efficiently pump HE-TOPAS-Prime). HE-TOPAS-Prime can be adopted to be driven by a variety of laser s...

TOPAS-Twins

TOPAS-Twins – two independently tunable optical parametric amplifiers 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 4-20um range. The energy for each OPA can be split to nearly any ratio internally while the specifications for each OPA are exactly the same as of TOPAS-C....

TOPAS-C

TOPAS-C has been replaced with TOPAS-Prime.

TOPAS-C is pumped by a fundamental harmonic of femtosecond Ti:sapphire laser amplifiers and continuously covers wavelength range from 1140 to 2600 nm. With optional frequency mixers this range can be extended down to 189 nm and up to 20 microns. White-light continuum is used as a seed source for ...

SHBC-TOPAS-400-WL

Second Harmonic Bandwidth Compressor (SHBC)- TOPAS-400-WL system is a nonlinear optics device devoted for generation of a narrow bandwidth (3-10 cm^-1) continuously wavelength tunable pulse when pumped by a femtosecond to picosencond pulse with bandwidth of 20-500 cm^-1.

SHBC- TOPAS-400-WL is pumped by a fundamental harmonic of femtosecond (picosecond) Ti:sapphire laser amplifiers and continuously covers wavelength range...

TOPAS-White

A non – collinear pumping scheme of an OPA is used when the collinear approach for the OPA 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 generation in a transparent medium possessing third order nonlinearity. The non-collinear geometry is used due to broad amplification bandwidth in the visible ...

TOPAS-800

TOPAS Model 800 is pumped by a fundamental harmonic of Ti:sapphire laser amplifiers and continuously covers wavelength range from 1150 to 2600 nm. With optional frequency mixers this range can be extended down to 189 nm and up to 20 microns. Can be switched between picosecond PS (1-4 ps) and femtosecond FS (35-300 fs) operation.

TOPAS-400

TOPAS Model 400 is pumped by a second-harmonic of Ti:sapphire laser amplifiers (1-4 ps) and continuously covers wavelength range from 470 to 2600 nm. With optional frequency mixers this range can be extended down to 189 nm and up to 5 microns (using an additional pump channel at 800 nm).

TOPAS-355

TOPAS Model 355 is pumped by a third-harmonic of Nd:YAG laser amplifiers (10-50 ps) and covers wavelength range from 417 to 2400 nm. With optional frequency mixers this range can be extended down to 189 nm and up to 20 microns (using an additional pump channel at 1064 nm).
