摘要：

KW-class　high-beam　quality　diode　laser　system　was　introduced　in　this　paper.　In　this　system,　the　wavelengths　of　808nm,　915nm,　940nm,　and　980nm　were　used　for　the　wavelength　coupling　and　polarization　coupling.　The　wavelength　coupling　and　polarization　coupling　can　reach　the　optical　efficiency　of　91.4%.　Before　wavelength　coupling,　polarization　coupling　and　beam　shaping,　the　maximum　output　power　of　the　laser　was　1200W,　and　after　that,　1031W　was　achieved,　so　the　overall　conversion　efficiency　reached　85.9　%.　12mm　•　mrad　of　the　output　beam　quality　was　realized　in　both　the　fast　axis　and　the　slow　axis.　Through　intelligent　control,　the　diode　laser　can　work　in　different　wavelength,　different　power　and　different　pulse　width.　Because　of　its　output　power　and　beam　quality,　this　laser　system　can　be　used　in　the　ultra-long-distance　laser　detection,　laser　remote　sensing　and　many　other　demands.　2009　SPIE.
