A 1.55 µm OP-VECSEL with electro-deposited copper substrate was optimized for lasing operation. It is a cost-effective solution compared with CVD diamond substrate assembled by metallic bonding. Experimental results showed that the effective thermal resistance Rth of a 60-µm diameter OP-VECSEL with ~150-µm thick copper substrate was 34±3 K/W. In plane concave cavity, maximum output power of 42,3mW was achieved at 25deg C when a 980nm single mode pump laser with pump power ~450mw was used, showing the potentiality of external cavity semiconductor disk lasers to generate mode-locked pulse train at 1.55 µm when it will be assembled with a fast saturable absorber mirror (SESAM).
