Abstract

We discuss and analyze concepts for the generation of tuneable continuous wave terahertz (THz) radiation with two color diode lasers. First, different geometries of two color lasers are reviewed. We show that the THz power of two color lasers in combination with external photomixers becomes sufficient for scanning THz imaging applications when optical amplification with a tapered amplifier is implemented. Then, the concept of direct emission of THz radiation out of a two‐color semiconductor laser is reviewed and the potential of this concept with respect to THz bandwidth and achievable THz power is critically analyzed.

## Abstract A CO‐bond cleavage of esters having a naphthyl group, NpCO‐OR and RCO‐ONp (Np=α‐ and β‐naphthyl (^α^Np and ^β^Np, respectively), R=Ph and Me), was found during the two‐color two‐laser flash photolysis in acetonitrile. The CO‐bond cleavage occurred when NpCO‐OR and RCO‐ONp were excited
