Abstract

Q-switched Nd-based lasers are used for a variety of medical and manufacturing applications and benefit from a high efficiency and stable diode pump, but limited commercially available solutions exist for single spatial mode direct pumping of Nd-based lasers at 885 nm. To satisfy this need, Freedom Photonics has developed ultra-robust watt-class diffractionlimited 885 nm diode lasers. We have demonstrated single-mode 885 nm diode lasers with an output power of <1.8 W (1 W rated) and 49% electricalto-optical efficiency. We employ facet passivation methods to protect against catastrophic optical mirror damage (COMD), and the optical power density we have demonstrated points to an effective facet passivation strategy. These devices may be used as high efficiency pumps for Nd-doped solid-state lasers.
