A halide material having general formula ArMAX is disclosed. The halide material can be processed to an optoelectronic film with a halogenated formamidine and a lead halide, and the optoelectronic film can be applied in the manufacture of an optoelectronic device like a perovskite laser or a PeLED. Experimental data have proved that, the fabricated optoelectronic film shows a property of photoluminescence (PL) peak wavelength adjustable. Moreover, the PL peak wavelength moves from 482 nm to 534 nm with the increase of the content of lead (Pb), halogen (X) and formamidine (FA) in the optoelectronic film. Furthermore, experimental data have also indicated that, the fabricated optoelectronic film can be used as a blue emissive layer, a red emissive layer or a green emissive layer, thereby having a significant potential for application in optoelectronics industry.

An apparatus and method of indirectly cooling an optomechanical resonator, comprising impinging a laser on an optomechanical resonator attached to a substrate, wherein the optomechanical resonator comprises a cantilever, a cooling end of the cantilever, having a cooling end comprising a laser-induced cooling element, an attachment end of the cantilever, attached to a substrate, and wherein the laser has a peak wavelength in the near-infrared band.

The present invention provides a way to use anisotropic laser gain media to make a laser that can lase in two longitudinal modes at different wavelengths with orthogonal polarizations. The two longitudinal mode (LM) laser output can be separated to generate two single LM outputs. This type of lasers can also be used to generate low noise continuous wave (CW) harmonics through intracavity harmonic generation.
