The heterogeneous direct bonding between Yb,Er:phosphate glass and Co:spinel crystal was achieved by surface activated bonding method. By using diamond-wire with thickness of 0.35 mm, the monolithic bonded-sample for eye-safe laser application was orthogonally sliced into four pieces without interfacial debonding.
