SILVER BULLET
TM
PRODUCT
CHARACTERISTICS
The Silver BulletTM is a fundamental building block for constructing high-power diode
laser arrays. Each Silver BulletTM consists of one to three mounted, CW laser diode
bars on a BeO substrate. These modules can be either mounted on customer supplied
heat exchangers or on a variety of heat exchangers offered by us. For customers
who wish to build their own arrays using these modules, a soldering kit is available
which contains a complete set of instructions. The Silver BulletTM was designed to be
a viable option for those developing new systems and to offer the flexibility to be
retrofitted into existing systems.
Every Silver BulletTM comes with a complete data packet which includes, P-I, V-I,
power conversion efficiency and wavelength spectrum. This data packet offers
customers the unique opportunity to have their own bars packaged, characterized,
and prescreened according to customer supplied specification before being mounted
on heat exchangers. Laser diode bar cavity lengths of up to 1 mm can be packaged
in the current configuration, and the package is easily adapted to custom applications.
The 980nm Silver BulletTM family consists of 20W CW, 1-bar arrays; 40W CW 2-bar
arrays; and 55W CW 3-bar arrays.

Laser diode product components are intended for use in a user-
devised end system.However, these products are capable of emitting
Class IV radiation. Extreme care must be exercised during their oper-
ation. Only persons familiar with the appropriate safety precautions
should operate a laser product. Directly viewing the laser beam or
exposure to specular reflections must be avoided. Serious injury may
result if any part of the body is exposed to the beam. The eye is
extremely sensitive to the infrared radiation and therefore, proper eye-
wear must be worn at all times. Use of optical instr uments with these
products may increase e ye hazard.Always wear proper e ye protection
when operating.
