DP series direct diode laser is developed and manufactured by Beijing Reci Laser Technology Co., Based on high reliable emitters and using engineering technologies such as spatial beam combination, popularization beam combination, wavelength beam combination, waveguide beam combination, fiber coupling and stripping cladding light, we have developed two categories of diode laser system-ones with high brightness and ones with high output power. Among them are DP series wavelength stabilized pump sources based on conductive cooled multiple emitter laser modules. They are for applications like pumping green, ultraviolet or ultrafast solid lasers as well as assistant long-range illumination, imaging, non-destructive examination of photovoltaic material and plastic welding, etc.
