We report on a high brightness fiber coupled single element laser diode and its assessment on various harsh conditions.The Ultra Compact Hermetic (UCH) modules (0.7 cm3) are manufactured using a totally glue free process owing toproprietary weld processes and a controlled inner atmosphere. They deliver up to 10W out of the fiber at 25 °C and morethan 8W at 60° C for λ=940nm. UCH modules emitting at 830nm also deliver more than 4.8W at 25°C. We report on therobust behavior of the UCH modules in harsh environment such as vibrations and exposure to radiationsKeywords: single emitter; laser diode; reliability.
