The sizes on the screen were larger than would be projected by aircraft at such a distance; image sizes were matched between the microlaser projector and the CRT device.
While the microLaser Turbo printers have the same popular features as Texas Instrument's other microLasers--including a small footprint, industry- standard emulations and advanced paper handling--they offer enhancements such as intelligent switching between interfaces and emulations without requiring user intervention.
Now, researchers have developed a microlaser that produces light from interactions between a mirrored cavity and atoms passing through that cavity one at a time.
Constructed from disks only 5 micrometers in diameter and mounted in air on a pedestal, this double-decker microlaser is considerably smaller than the tiny semiconductor lasers that scan discs in compact-disc players.
Resembling a miniature thumbtack, the novel microlaser consists of a layered disk only 400 or so atoms thick mounted on a slender pedestal.
WGM lasing from blue colloidal liquid has been demonstrated in ternary CdZnS/ZnS alloyed core/shell QDs, and quasi-disk WGM microlasers have been realized via a simple modification of the surface tension of water, which deforms the lasing cavity, and this deformation can be used to modify the lasing peaks [42].
"The optoelectronic tweezers and freeze-drying technique can be used to not only assemble solder beads, but also to assemble a broad range of objects such as semiconductor nanowires, carbon nanotubes, microlasers and microLEDs," said Zhang.

Feedback-coupling in microlasers will allow us to explore the limits of a classical description of chaotic laser dynamics via the Lang-Kobayashi rate equations and to develop an advanced model taking cQED- and QD-specific effects into account.
Meanwhile, according to Miriam Serena Vitiello, group leader of Terahertz Photonics Group, future goals are to push performance in the ultra-fast detection realm, explore the feasibility of single photon detection by using novel architectures and material choices, develop compact focal plane arrays and to integrate on-chip the nanowire detectors with THz quantum cascade microlasers.
He and his colleagues were able to reliably distinguish ring-stage red blood cells (RBCs) from uninfected RBCs "despite the very small size of hemozoin, 50-100 nm." "If this technology can be made cheap and field deployable," says Dvorin, "I think that it might really change the field of malaria diagnostics." That technology depends on microlasers that at this point are costlier than the RAM components.
