…continuously downscaled. Such trends
motivate the ongoing development of suitable excimer laser
sources and optical beam delivery systems for the most
appropriate 308 nm wavelength. Excimer lasers deliver the
high pulse energies required to support the large processing footprint…
…refractive index and alters the polarization of the incoming light; an appropriate combination of
polarization-sensitive optics can be placed in the cavity to prevent light of altered polarization from circulating.
Other types of lasers, such as excimer lasers, do not require a Q-switch…
…some point in the
process flow the OLED display is removed from the temporary glass carrier. Typically, this is
accomplished using an excimer laser-based technique called Laser Lift-Off.
While the details of where and how the OLED display is separated from the carrier vary among
…Most commonly, this is accomplished with a pyroelectric detector, which is based on a ferroelectric crystal having a permanent electrical polarization. Incident light heats the crystal, changing its dipole moment and causing current to flow. This electrical signal is processed through carefully…
…range of applications, supported in turn by a broad spectrum of lasers, including CO 2 , fiber, direct-diode, diode-pumped solid-state (DPSS) and excimer lasers. This market is huge and diverse - far from monolithic - and new process developments or significant advances in laser technology are…
