JMAR’s Nd: YAG CW Diode Pumped Solid State laser development is the result of many years of research and development. JMAR’s design technique allows for the creation of a variety of configurations. Some of the key advantages of JMAR’s lasers are:
|
High Brightness
High Beam Quality (less than 5x DL)
Short Pulse Duration (as low as 1ns)
High Repetition Rate (up to 5kHz)
Building Block Architecture Provides Multiple Design Options
