Embedded optical sensors always require more compact, stable, and powerful laser sources. In this Letter, we present a fully integrated passively Q-switched laser, which has been realized by a Ag + / Na + ion exchange on a Nd 3 + -doped phosphate glass. A BDN-doped cellulose acetate thick film is deposited on the waveguide, acting as an upper cladding and providing a distributed saturable absorption. At λ = 1054 nm , the device emits pulses of 1.3 ns FWHM with a repetition rate of 28 kHz . These performances, coupled with the 1 kW peak power, are promising for applications such as supercontinuum generation.
