Lasers with emission wavelengths longer than1.4μm are often called “eye-safe”, which are far less dangerous than 1-μm lasers with similar output powers. Shalom EO developed the eye safe micro laser module with the wavelength of 1535nm that used in many applications such as laser range finder, Lidar and medical treatment and run properly in the extreme environment with the temperature range of -40℃~65℃. In the future, Shalom EO will concentrate on supplying more health and safe products for you. This device uses a single laser diode at 940nm to end pump a Er,Yb:glass gain media. A Co2+:MgAl2O4 passive Q-switch is used to produce nanosecond level pulses at a repetition rate from single shot to 10 Hertz, which is sufficient for ranging to over 2 kilometers. The Eye-safe Micro laser was designed and demonstrated to operate over a wide temperature range without temperature control of the pump laser. An desirable feature of Er,Yb:glass lasers is that they emit directly at 1.54 microns, which is important for eye safe operation and low cost fabrication.
