GEM DPSS CONTINUOUS WAVE LASER SERIESPERFORMANCE DATAFLEXIBLE DESIGN

The gem range is a series of compact lasers designed for easy OEM
integration. With a wide power range and multiple wavelength
offerings, the gem is ideal for system designers requiring a reliable,robust laser with excellent beam quality. All gem lasers are highspecification single transverse mode CW lasers, ideal for many
applications such as Raman and super-resolution microscopy.
The gem range has a long industrial heritage, delivering extended
performance lifetimes that truly enable it to be treated as a black box to be installed and forgotten (Fig. 1).

Customizable options available for your laser to optimize yourapplication.
• Fiber coupling: Available with multi or single mode fiber delivery
options which allows the beam to be delivered to the point ofneed.
• Intelligent control unit: Allows easy setting and monitoring ofthe laser parameters. Incorporating PowerLoQ™ technology, thegem lasers show extreme power stability over long periods ofuse.

400• 1200 g drop-test: (Fig. 2) All gem lasers undergo a drop test
to check that all components are correctly fitted prior to its
extended 300 hour test period. This rigorous testing regime
ensures long operational lifetimes.
