David Welford, Ph.D. founded Endeavour Laser Technologies in 1999 to provide clients with highly innovative, practical and cost-effective optics solutions for difficult laser engineering problems.
Dr. Welford’s 30-plus years of expertise covers laser systems operating from the UV to mid-IR in the single-frequency to ultrashort pulse regimes. Specific laser materials expertise includes Nd:YAG, Nd:YLF, Nd:YVO4, Nd:YSGG, Nd:GSGG, Yb,:AYG,Cr:Nd:GGG, Ho:YAG, Er:YLF, Er:YAG Yb, Er:glass, Co:MgF2, Ti:Al2O3, Cr:YAG and 1-micron to 2-micron fiber lasers. Specific nonlinear optics experience includes harmonic generation of 1-micron and 1.3-micron lasers to UV and visible wavelengths using KTP, LBO, BBO and LiIO3 and optical parametric oscillators using KTP, KTA and CdSe to cover most of the visible to 10-micron region. Dr. Welford is also an experienced user of Winlase and SNLO.

Dr. Welford holds a Ph.D in physics from Imperial College of Science and Technology, London, UK where he researched modelocked dye laser technology and organic dye photo-dynamics. In 1980 he began a seven year tenure at M.I.T. Lincoln Laboratory, investigating the fundamental spectral and modulation characteristics of diode lasers for application in optical communications systems. From 1987 until 1999, Dr. Welford developed solid-state laser technology and products for scientific, military and commercial applications as a senior scientist at Q-Peak, Inc.

Dr. Welford has over 40 peer-reviewed publications, 5 patents and is co-author of the chapter on “Miniature Solid-State Lasers,” in the Handbook of Photonics (second edition) published by CRC Press in 2007. Dr. Welford is also a member of the Optical Society of America and the Institute of Electrical and Electronic Engineers.
