Dr. David Welford, founder of Endeavour Laser Technologies

Endeavour Laser Technologies specializes in the development and application of laser-based systems, particularly those that use solid-state lasers and diode lasers, including diode-pumped solid-state (DPSS) lasers. Dr. Welford’s expertise covers laser systems operating from the UV to mid-IR in the single-frequency to ultra-short pulse regimes. Specific laser materials expertise includes Nd:YAG, Nd:YLF, Nd:YVO4, Nd:YSGG, Nd:GSGG, Cr:Nd:GGG, Er:YLF, Er:YAG Yb, Er:glass, Co:MgF2, Ti:Al2O3 and Cr:YAG. 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 1.3-micron to 10-micron region.

Dr. Welford holds a Ph.D in physics from Imperial College of Science and Technology, London, UK. He began his career in 1977 with research in modelocked laser technology at Imperial College of Science and Technology in London. 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. (formerly Schwartz Electro Optics.) Three examples of new technology he successfully commercialized are:

  • The first demonstration of room‑temperature operation of the Co:MgF2 laser system recognized in Optics News as a significant advance in the field of optics in 1988, and the development of a commercial Co:MgF2 laser product.
  • The development and introduction of the first commercially available sub-picosecond mode-locked cw Ti:Al2O3 laser, the Titan-ML, the winner of a Product Award in 1991 from Photonics Spectra.
  • The development of a compact, rugged, diode-laser-pumped, 10 W Q-switched Nd:YVO4 laser system, the Aero-1064, for military and commercial applications.

Dr. Welford has over 40 peer reviewed publications,
4 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.
