Popis: Room temperature upconversion in Nd doped fluoride glasses excited with a cw diode laser is reported for the first time. With 801 nm diodes, efficiencies are high enough for the protected eye to see white light with pump powers as low as 10 mW. In addition, near-UV emission is produced. Upconversion spectra are presented for a range of fluoride glasses between 800 and 350 nm, together with excitation spectra and efficiency estimates. Possible mechanisms for two and three photon excitation processes are suggested.
