TAMPERE, Finland, July 1, 2014 — A high-power laser diode driver, the Intensify Nx50 from Granite Devices has parallel connection capability for the OEM market.
The device can scale up continuous and pulsed output current rating to 150 A. The device accepts standard 12 V DC input voltage while output current is adjustable from 0 to 50 A. The maximum output voltage of 5.0 V allows two laser diodes in a series connection.
Intensify employs high-frequency, three-phase switching conversion to minimize output ripple and physical size, eliminating the need for active cooling.
The device includes under-voltage, over-temperature, electro-static discharge and laser diode protections as standard features. The driver is suited for OEM laser diode applications such as optical pumping, material processing and printing.
- optical pumping
- The process whereby the number of atoms or atomic systems in a set of energy levels is changed by the absorption of light that falls on the material. This process raises the atoms to specific higher energy levels and may result in a population inversion between certain intermediate levels. The optical pumping of an optical medium within a laser cavity is one of the fundamental processes involved in the generation of a beam.
