AVUS


OPA

The APE Optical Parametric Amplifier provides widely tunable high energy pulses at high repetition rates. It is the optimal light source for multi-photon interaction, spectroscopy and microscopy.

High power OPA

AVUS is the very latest Optical Parametric Amplifier (OPA) providing widely tunable high-energy pulses. It is ideal for use with 1 μm femtosecond lasers.

Intro

AVUS Optical Parametric Amplifier

AVUS is the very latest Optical Parametric Amplifier (OPA) providing widely tunable high-energy pulses. It is ideal for use with 1 μm femtosecond lasers and opens doors for up to 50 W pump power.
The user-friendly and maintenance-free unit is air-cooled and constructed with a monolithic case design for long-term thermal stability, even at maximum pump power.
The fully-automated and alignment-free unit covers a wide wavelength range, while the integrated tuning and automatic wavelength separation of the AVUS maintain the same beam position and direction for all wavelengths.

Application Examples

  • Nonlinear microscopy
  • Femtosecond pump probe spectroscopy
  • Time-resolved spectroscopy and Photoluminescence (TR3, TRPES, TRPL)
  • Photoelectron-photoion coincidence spectrometry (PEPICO)
  • Coherent anti-Stokes Raman Spectroscopy (CARS)
  • Two-dimensional infrared spectroscopy (2D-IR)
  • Terahertz emission studies
Features
  • OPA for 1 μm pump laser
  • 50 W maximum pumping power
  • Air-cooling and monolithic case for long-term temperature stability
  • Tunable from 210 nm ... 11 μm (UV, VIS, IR)
  • Completely automated and fully computer controlled
  • Long-life operation with sealed inner case to protect sensitive components
  • TCP/IP remote control with standardized command set for easy programming
  • 24/7 integrated performance monitoring of both laser system and AVUS
  • No need for external beam routing or separation: the integrated tuning and automatic wavelength separation maintain the same beam position and direction for all wavelengths.
