OL 1995: High-energy, high-efficiency harmonic generation from a Cr:LiSrAlF6 laser system

H. H. Zenzie and Y. Isyanova, Research Division, Schwartz Electro-Optics, 45 Winthrop Street, Concord, MA 01742

We have developed a near-diffraction-limited Q-switched Cr:LiSrAIF6 (Cr:LiSAF) laser system capable of producing 860-nm, 400mJ pulses at a repetition rate of 2 Hz. Our harmonic-generation experiments with β-BaB2O4 nonlinear crystals have yielded 200 mJ of energy at 430 nm and 40mJ at 215 nm.

To the best of our knowledge, the 50% second-harmonic conversion efficiency and UV energy demonstrated in this research are the highest yet obtained from a Cr:LiSAF laser. 0146-9592/95/020169-03 ©1995 Optical Society of America

JSTQE 1995: Nonlinear conversion of Ti:sapphire laser wavelengths

Glen A. Rines, Member, IEEE, Henry H. Zenzie, Richard A. Schwarz, Senior Member, IEEE, Yelena Isyanova, and Peter F. Moulton, Senior Member, IEEE Invited Paper

We review a series of experimental investigations into the use of nonlinear optics to shift wavelengths generated by the tunable Ti:sapphire laser. We consider two basic approaches: harmonic generation (and the related process of sum frequency generation) to reach shorter wavelengths, and optical parametric generation to cover longer wavelengths.

Both techniques have been aided by the development of two sets of nonlinear crystals, the borates BBO and LBO for harmonic processes, and the KTP family of materials for use with optical parametric generation. In combination we have used nonlinear techniques to produce tunable wavelengths ranging from 193-3000 nm.

ASSL 1999: Efficient Third Harmonic Conversion of Ti:Sapphire Laser Radiation

Alex Yu. Dergachev, Peter F. Moulton, Bhabana Pati Q-Peak, Inc.,
135 South Road, Bedford, Massachusetts 01730 Tel.: (781) 275-9535, FAX: (781) 275-9726, E-mail: dergachev@qpeak.com

For the first time, to the best of our knowledge, we report the highest efficiency of 35% (overall efficiency) for frequency tripling of Ti:Sapphire laser radiation in LBO (Type I) crystal. TEM00 injection-seeded Ti:sapphire laser was operated in 920-960 nm range to provide 307-320-nm UV light for ozone LIDAR applications.

Precursor of OSA-managed meetings

  • The Ti:sapphire laser was the result of about a decade of concentration on a single idea
    • tunable solid state lasers
    • it meandered about through II-VI semiconductors, TM- doped fluorides, RE-doped oxides and landed on a variation of the ruby laser. It was built on a foundation of outright failures and partial successes.
  • Thank you -Bell Labs, MIT Lincoln Laboratory, Aram Mooradian, Livermore Laboratory/DOE, the US Air Force, Bill Schwartz, NASA
  • Thank you (not) -MIT Patent Office (the old one)
  • Guess that over $100 million in laser systems have resulted
