Coherent TOPAS Ultrafast OPA

The TOPAS is a computer-controlled optical parametric amplifier (OPA) used to extend the tuning range of the Legend Elite, Legend Elite Cryo PA, Hidra and Libra amplifiers.

TOPAS-Prime is the newest generation of computer-controlled optical parametric amplifiers (OPA) providing the ability to extend the tuning ranges of the Astrella, Legend Elite HE+ and Libra ultrafast amplifier families. All of the best features from the TOPAS-800-fs are retained in the TOPAS-Prime including white light seeding for lowest output noise performance. In addition, TOPAS-Prime employs a monolithic housing for improved mechanical stability. TOPAS-Prime uses a modular design and wavelength extension packages to achieve a tuning range of 190 nm to 20 µm.

Features:

• Monolithic housing for mechanical stability
• Computer-controlled tunable output
• Energy conversion >30% to 35% to parametric light
• Low output noise due to whitelight seeding
• Optional fresh pump channel for improved sum frequency performance
• Modular option for extended tuning from 190 nm to 20 µm tuning range, standard tuning is from 1150nm to 2600nm
• Configurations to accommodate pulse widths from all Coherent kHz femtosecond amplifiers (<130fs, <50fs, <40fs, <35fs and <25fs)
• Multiple OPA's can be pumped with one Ti:S amplifier
• High pump-energy models available (up to 20 mJ)
