Verdi G-Series

Verdi G-Series

…the rod-based gain medium is replaced with a robust and versatile semiconductor chip. OPSL output power can be changed without affecting beam parameters due to the ultra-thin gain medium (i.e. no thermal lensing issues). In addition, the short upper-state lifetime of the OPS chip removes the “green…

…advanced chip architectures. As silicon wafers get thinner and new material layers are added, lasers are playing a critical role in processing these wafers. As wafers get thinner, they become more difficult to process with traditional saws due to increased cracking and chipping. DPSS UV lasers…

gain chip drastically reduces the demands on the pump
geometry, one of the attributes allowing the power of
OPSL technology to be scaled from the milliwatt to
multi-watt range. Efficient rear-surface cooling of the
chip also means that there is no thermal lensing in the
gain

…powers
up to 300 mW. Output powers of up to 500 mW can be
reached with slightly larger Sapphire HP models. Plus
the thin (10 µm) gain chip is effectively cooled from its
rear surface and does not create a thermal lens.
Together, this enables the power of any Sapphire laser…

…for any
arbitrary output wavelength across much
of the visible and near-UV spectrum,
merely by tweaking the design of the gain
semiconductor chip. For example, new
lasers at 588 and 594 nm were recently
introduced for exciting orange fluorophores. Other models at 550 nm…

…single chip.
In order to effectively increase the package density, the reduction along the lateral dimensions must not be gained at the
expense of the vertical device dimensions
as exemplified in figure4. From a manufacturer`s perspective, this means that
individual chips, and…

…cold processing
achieved with the laser removes material to produce a
cutting edge which is of a very high quality and is free
of chips. For materials with large granularity, the laser
can even ablate a part of a diamond grain to maximize
smoothness. This quality level is…

…is an old
technology, with only small, incremental
improvements occurring. Automated,
easy-to-use box types of confocal are
gaining popularity as they solve the complexity issue that has plagued traditional
confocal systems. Ongoing improvement
of scientific-grade…
