FDL-780-1W-TA Tapered Amplifier for MOPA

GaAs based tapered amplifiers are used for the amplification of an existing seed laser. The seed power between 10mW and 30mW can be amplified up to nearly diffraction limited power values of 1000W. Such a setup is called MOPA(Master Oszillator Power Amplifier). The rear facet and the front facet are both provided with an anti-reflection coating of less than 0.01% to avoid laser action of the amplifier chip itself. Application examples for MOPA setups with tapered amplifiers are optical cooling, optical traps of high resolution absorption or Raman spectroscopy.
