In the basic Diode-Pumped Alkali Laser device, excitation to the n 2P32 electronic level by a single diode laser pump source leads to a population inversion between the first excited electronic 2P12 level and the ground 2S12 level, permitting the construction of efficient, high-power, compact DPAL laser oscillators in the near infrared spectral region. The folded stacked package includes a flexible board or substrate comprising first, second and third device packaging units, and first and second folding unit units. A synchronizing circuit sequentially reads data from the medium and data stored in the buffer memory prior to the interruption and synchronizes the read and stored data. The first contacts comprise a power segment and a signal segment. If the call frequency reaches the default call frequency N, the communication device blocks a phone number of the incoming call. The inhibitors of the invention can also be attached to surfaces to provide for removal of nucleases from media, solutions or other liquids in contact with the solid.
