Abstract: This application is applicable to the field of communications technologies, and provides an embedded subscriber identity module (eSIM) card identification method and a terminal device method. The method includes: after completing an initialization process, driving an eSIM card to be powered on; querying whether an activated profile exists in the eSIM card; and when a query result is that no activated profile exists in the eSIM card, powering off the eSIM card. When the eSIM card is not activated or no activated profile exists in the eSIM card, it indicates that a user does not need to use a related function or service of the eSIM card. In this case, the eSIM card is powered off. When the eSIM card is not activated, it means that no profile exists in the eSIM card.

Abstract: A wavelength-tunable, ultrafast laser includes a resonator having an optically-pumped gain-medium. The resonator includes a pair of group-delay-dispersion compensating prisms and a bandwidth limiting stop. Both prisms and stop are fixed in a predetermined position relative to one another. In one embodiment, a movable beam shifting reflector is placed between the prisms. The reflector shifts the dispersed beam with respect to the second prism and the stop. The stop is arranged, cooperative with the second prism, to select a pulse wavelength within the gain-bandwidth. Tuning of the selected pulse-wavelength is accomplished by translating the beam shifting reflector. Alternatively, a two-reflector arrangement may also select pulse-wavelengths, accomplished by a combination of rotation and translation of the two reflectors.

Abstract: An original laser-radiation beam having a symmetrical M2 but poor beam quality is sliced in one transverse axis, by a fanned-out stack of parallel transparent plates, into a plurality of beam slices. The beam-slices are also spread by the stack of plates in another transverse axis perpendicular to the first axis. A fanned-out stack of glass blocks aligns the spread beam-slices in the first axis to form what is effectively a single beam having an asymmetric M2, with beam quality improved in one axis and degraded in the other compared with the original beam. The effective single beam is projected into a line of radiation by a cylindrical lens, or by a homogenizing projector including spaced apart cylindrical lens arrays followed by a spherical condenser lens.
