TRPL specifications

Optical excitation:

• Ti:sapphire fs/ps oscillator (Mira-900 dual):
  wavelength: 700-1000 nm
  external second harmonic: 350-500 nm
  external third harmonic: 233-333 nm
  pulse duration: 250 fs/1.5 ps at 76 MHz repetition rate
  
  
• Optical parametric oscillator (OPO PP):
  fundamental wavelength: 1010-1500 nm
  internal second harmonic: 505-750 nm
  external fourth harmonic: 253-375 nm
  pulse duration: 250 fs/1.5 ps at 76 MHz repetition rate
  
  
• Pulse picker to reduce the repetition rate of the Mira
  to the frequency range between 2.4 kHz and 4.8 MHz
