The new FERT-1535-XXXµJ-Q is a series of "eye-safe" 1535nm diode-pumped passively q-switched Erbium glass lasers with pulse energies between 40µJ to 2000µJ and peak powers between 10kW and 133kW. The output beam has a diameter of 0.2mm with divergence ≤12mrad. The operating temperature range is very wide and covers a range from -40°C to +65°C. With dimensions of just 34mm x 18mm x 7.7mm (LxWxH) they are very compact. These features and the high reliability make them the optimal laser source for applications like laser range-finding, laser imaging and surveying equipment.
