JOSA B 2004: Single-frequency operation of a Cr:YAG laser from 1332 to 1554 nm

David Welford and Martin A. Jaspan Q-Peak Inc., 135 South Road, Bedford, MA 01730 D. Welford is now with Endeavour Laser Technologies, P.O. Box 174, Hathorne, MA 01937
M.A. Jaspan is now with the Quantum Imaging Laboratory, Dept. of Electrical and Computer Engineering, 8 Saint Mary's Street, Boston, MA 02215-2421

We report the first demonstration to our knowledge of broadly tunable, single-frequency operation of a cw Cr:YAG laser. Single-frequency operation was obtained from 1332 to 1554 nm with a maximum output power of 680 mW generated at 1457 nm with 10% conversion efficiency of 1047 nm pump laser radiation.

A traveling-wave ring resonator was forced to operate unidirectionally by use of Faraday rotation in the CrYAG gain medium with a nonplanar resonator alignment, providing the required compensating polarization rotation. Tuning was accomplished with a single-plate birefringent tuning element, and single-longitudinal-mode operation was obtained by the addition of a 9.5 nm thick uncoated CaF2 etalon. An instrument-limited single-frequency linewidth of 2.3 MHz was measured. © 2004 Optical Society of America OCIS codes: 140.3570, 140.3600

ASSP 2005: History of ASSP and Tunable Solid State Lasers

Peter F. Moulton, Q-Peak 135 South Road, Bedford, MA 01730

Peter F. Moulton, Schwartz Electro-Optics; discusses History of ASSP and Tunable Solid State Lasers. 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.

• OL 1995: Diode-pumped, single-frequency Cr:LiSrAlF6 ring laser

H. H. Zenzie, A. Finch, and P.F. Moulton, Research Division, Schwartz Electro-Optics, 45 Winthrop Street, Concord, MA 01742

We report the development of a tunable, diode-pumped Cr:LiSrAIF6 ring laser that emits as much as 43 mW of power in a single longitudinal mode at 849 nm. By tuning the output with a birefringent filter, we achieved single-frequency operation from 810 to 860 nm. The short-term (10-s) frequency stability was better than 15 MHz. 0146-9592/95/212207-03 © 1995 Optical Society of America.
