We present coding methods for protecting against tampering of write-once optical disks, which turns them into a secure digital medium for applications where critical information must be stored in a way that prevents or allows detection of an attempt

Blue upconversion laser operation in Tm:YLiF4 at 450.2 nm on the 1D2→3F4 transition, and at 483.0 nm on the 1G4→3H6 transition has been achieved using cw pumping with Ti Sapphire and DCM dye lasers. The 450.2‐nm laser was excited by sequential

Two new laser transitions are reported for the Er3+ ion in YLiF4: in the blue at 469.7 nm and in the green at 560.6 nm. These are pumped with red and near‐infrared laser radiation using nonlinear excitation processes in which more than one upconver

Compact Blue-Green Lasers.
Compact, efficient, diode-laser-based blue light sources are useful for many applications including optical storage and laser printing. Blue light can be generated by frequency doubling the output of reliable, high-power 860-nm lasers in potassium ni

There is currently considerable research on compact blue light sources that use periodically-poled waveguides for quasi-phasematched frequency doubling of GaAlAs laser diodes.1,2 For such devices to become practical, they must be configured in such a
