SINGLE-PUMP MULTI-WAVELENGTH LASING SEMICONDUCTOR RAMAN PUMP LASER AND PUMP COMBINATION APPARATUS

摘要

A single-pump multi-wavelength lasing semiconductor Raman pump laser comprises a thermoelectric cooler arranged in a shell; a heat transition bearing platform arranged in the thermoelectric cooler; a semiconductor Raman pump laser tube core arranged on the heat transition bearing platform; and a coupling lens group , a thermistor and a backlight detector that are arranged on the heat transition bearing platform respectively. The pump laser tube core, the backlight detector, the thermistor and the thermoelectric cooler are electrically connected to pins outside a laser tube shell. A pump combination apparatus comprises a first signal transmission fiber, a pump signal combiner and a second signal transmission fiber that are sequentially connected to each other. An input terminal of the pump signal combiner is connected to an output terminal of an isolated polarization beam combiner and depolarizer. Two polarization maintaining fiber input terminals of the isolated polarization beam combiner and depolarizer are correspondingly connected to one single pump multi-wavelength lasing semiconductor Raman pump laser respectively.
