Toptica BoosTA Semiconductor Laser Amplifier

BoosTA 01

  • Compact and economic optical amplifier
  • Ideally suited to amplify TOPTICAs diode lasers,
    also suited for third party products
  • Wavelength range 649 .. 1083 nm
  • High power, up to 1.5 W
  • Nearly diffraction limited output beam with suitable master oscillator
    (M² typ. < 1.5, fiber coupling efficiency typ. 60 %)
  • Integrated driver concept, most compact
  • Computer controlled (RS 232)
The BoosTA is a compact and economical optical amplifier. Just put light into it, and it amplifies it up to a factor 100. The spectral properties of the master laser are preserved. The BoosTA includes computer controlled integrated electronics, and all optics for accepting a collimated and linearly polarized input beam. Custom optics and good thermal management guarantee best performance.
