  • Pulse-on-Demand Modules

May 2011
ALPhANOVRequest Info
The Alphanov Optical and Laser Technological Center presents the PDM series pulse-on-demand OEM modules that produce optical pulses with controlled temporal shape. From single shot to continuous wave, with pulse lengths from 1.5 ns to any required pulse burst configuration, they reproduce exactly the user’s input TTL/LVTTL numerical signal with nanosecond rise times and up to 1.7-W peak power. Available wavelengths are 976, 1030, 1064 and 1075 nm, repetition rate is up to 250 MHz, and beam quality is M2 <1.2. Minimum full width half maximum pulse width at 150-mW peak power is 1.5 ns, and maximum spectral bandwidth is 1 nm. The modules feature manual and analog signal peak power adjustment. Options include polarized fiber, an output isolator and a narrow-emission bandwidth of <30 MHz.

fiber laser
A laser in which the lasing medium is an optical fiber doped with low levels of rare-earth halides to make it capable of amplifying light. Output is tunable over a broad range and can be broadband. Laser diodes can be used for pumping because of the fiber laser's low threshold power, eliminating the need for cooling.
The science of sensing and measuring information at some remote location and transmitting the data to a convenient location for reading or recording.
