Please send queries about the products below to r.szipocs@szipocs.com   ULTRAFAST OPTICS AND SERVICES OPTICS R&D Ultrafast Lasers Ltd. offers different kinds of ultrabroadband and/or dispersive dielectric mirrors utilizing our patented chirped mirror technology (US patent 5,734,503). The mirrors are optimized for different applications: MCGTI optics. Low-loss, Multicavity Gires-Tournois type dispersive dielectric mirrors developed for Mirror-Dispersion-Controlled mode-locked Ti:S, Cr:LiSAF, Cr:LiSGaF, Yb:KGW, Yb:glass, etc. lasers. View datasheet UBCM optics. Ultra-broadband mirror set for broadly tunable femtosecond Ti:sapphire lasers (Xwave or Xband optics). View datasheet Chirped mirror optics. Chirped mirrors for linear group delay vs. frequency control in optical parametric amplifiers (OPA-s) or in white light continuum experiments in the visible and NIR. View datasheet   ULTRAFAST LASERS AND SERVICES LASERS R&D Ultrafast Lasers Ltd. offers three basic types of Ti: sapphire laser oscillators utilizing our patented chirped mirror technology (US patent 5,734,503). The lasers are optimized for different time resolved spectroscopic applications: FemtoRose 10 MDC/PRC is developed for applications where sub-10-fs pulses around 800 nm are required. Positive dispersion of a 2 mm thick gain medium is compensated purely by chirped mirrors (MDC) or by fused silica prism pair with proper chirped mirrors (PRC). View datasheet FemtoRose 20 PRC is developed for applications where sub-20-fs pulses around 800 nm are satisfactory. In this configuration, material dispersion of a 4 mm thick gain medium is compensated by combining fused silica prism pairs with chirped mirrors. The available mode-locked output power is even higher in this case than for our FemtoRose 10 MCD laser. Changing prism insertion, the pulse duration of the mode locked pulses can be varied in the 15 - 50 fs range. View datasheet FemtoRose 20 MDC is developed for applications where sub-20-fs pulses around 800 nm are satisfactory. In this configuration, material dispersion of a 4 mm thick gain medium is compensated by a low loss negative dispersion dielectric mirror compressor with no intracavity prism pairs. The laser provides high mode-locked output powers up to 550 mW with sub-20-fs pulse duration when pumped by a 5 W Millennia laser. View datasheet FemtoRose 100 MDC COMPACT is developed for applications such as imaging by nonlinear microscopy, where ~80-150 pulses at a fix wavelength around 820 nm are satisfactory. In this configuration, material dispersion of a 4 mm thick gain medium is compensated by a low loss negative dispersion dielectric mirror compressor with no intracavity prism pairs. This laser has a built in DPSS pump laser for better stability. View datasheet FemtoRose 100 TUN is developed for applications where tunable femtosecond laser pulses of 80-150 fs duration are required. In this laser configuration intracavity dispersion is compensated by an SF10 prism pair due to the relatively long Ti: sapphire crystal. The wavelength tuning element is a single plate birefringent filter. The laser can be tuned within the 710-980 nm wavelength range with pulse durations < 100 fs. View datasheet FemtoScope is a femtosecond pump-probe system for measuring ultrafast absorption kinetics of transparent or reflective samples. The small change in the absorption is detected by a digital lock-in amplifier system using 24 bit A/D converter. View datasheet FemtoRainbow 100 OPO is a widely tunable synchronously pumped infrared OPO developed for spectroscopic (pump-probe spectroscopy, time resolved fluorescence spectroscopy) applications. The frequency conversion is made by a KTP or PPLN crystal depending on the end user’s requirement. For time correlated single photon counting experiments the use of KTP crystal is "enough" to produce UV, visible or IR photons by sum frequency or second harmonic generation. In this case the output of the OPO can be changed by tuning the pump Ti: sapphire laser. For pump-probe experiments the use of PPLN is adequate, the frequency of the generated photons can be changed by two independent ways: tuning the wavelength of the Ti:S laser or changing the period of the PPLN sample. FemtoRainbow 100 produces ~100 fs pulses. View datasheet
