Company Profile
Product Details
Erbium and Ytterbium co-doped phosphate glass is one of the best
suitable materials for lasing at 1.54m, a wavelength which is well
used in‘eye safe’applications. Also, features of the Er glass
includes high optical quality, slope efficiency and wide pump band.
Since its outstanding properties as a laser medium, there are
several manufacturers having developed an extensive range of Eye
Safe Erbium Glass Transmitters for use in different kinds of Laser
Rangefinders and Medical Equipment. This range of glass laser
transmitters covers Flash Lamps and Diode types of pumping, a broad
spectrum of Output Energy, Repetition Rate, Pulse Width, conductive
and air-forced cooling and using Passive and Active Q-switches. The
Erbium glass nanosecond laser transmitter manufacturing facilities
include three levels of Clean Rooms: ISO 7 (Class 10.000), ISO 6
(Class 1.000) and ISO 5 (Class 100), Laminar Boxes, numerous
standards and special Electro-Optical instruments and jigs. These
facilities include a separate department that specializes in
manufacture of unique active Q-switch based on FTIR principle.
