Mode-Locked Erbium/Ytterbium Co-Doped Waveguide Laser

May 1, 2001
Author(s)
John B. Schlager, Berton Callicoatt, Kevin L. Silverman, Richard Mirin, Norman Sanford, D. L. Veasey
Picosecond pulses are generated from a passively mode-locked ER3+/Yb3+ co-doped planar waveguide laser in an extended cavity configuration with a semiconductor saturable absorber mode locker. Average output power exceeds 8 mW and is expected to increase

Single-frequency and Mode-locked Er/Yb Co-doped Waveguide Lasers

Berton Callicoatt, John B. Schlager, Kevin L. Silverman, Robert K. Hickernell, Richard P. Mirin, Norman A. Sanford, Joseph S. Hayden, Samuel D. Conzone, Robert D. Simpson
We present results for single-frequency and mode-locked Er/Yb co-doped waveguide lasers. The single-frequency DBR waveguide lasers have output power in excess of 80 mW with laser linewidth of 17 kHz. The passively mode-locked waveguide lasers produce

Yb/Er-Codoped and Yb-Doped Waveguide Lasers in Phosphate Glass

D. L. Veasey, David S. Funk, P. M. Peters, Norman Sanford, Gregory E. Obarski, N. H. Fontaine, M. Young, A P. Peskin, W. Liu, S. N. Houde-Walter, Joseph S. Hayden
We present experimental and theoretical results of our recent work on the development of waveguide lasers using rare-earth-doped phosphate glasses. An improvement has been achieved over previously reported waveguide laser results using the process of ion

Dual wavelength, 980 nm-pumped, Er/Yb-codoped waveguide laser in Ti:LiNbO 3

March 5, 1998
Author(s)
J. Amin, J. A. Aust, D. L. Veasey, Norman Sanford
The authors demonstrate the first Er/Yb codoped waveguide laser in Ti:LiNbO 3. The device was fabricated on x-cut LiNbO 3 with the guides parallel to the x-axis resulting in reduced photorefractive damage and allowing 980nm pumping. Laser operation is

980 nm-pumped Er- and Er/Yb-doped waveguide lasers in LiNbO 3

J. Amin, J. A. Aust, D. L. Veasey, Norman Sanford
We demonstrate a 980 nm-pumped Er- and the first Er/Yb-doped waveguide laser in Ti:LiNbO 3. The devices were fabricated on x-cut LiNbO 3, with the guides parallel to the z-axis. This choice of waveguide orientation results in a reduced susceptibility to

Z-propagating waveguide lasers in rare-earth-doped Ti:LiNbO 3

December 16, 1996
Author(s)
J. Amin, J. A. Aust, Norman Sanford
A means of reproducibly fabricating stable cw lasers in rare-earth-doped Ti:LiNb0 3 has been demonstrated through judicious choice of waveguide orientation. Z-propagating waveguides have been fabricated in Nd- and Er-diffused Ti:LiNb0 3 and room

Passively Q-switched Nd-doped waveguide laser

November 15, 1994
Author(s)
J. A. Aust, K. J. Malone, D. L. Veasey, Norman Sanford, Alexana Roshko
A passively Q-switched waveguide laser operating at 1.054 υm has been demonstrated in a Nd-doped phosphate glass. The channel waveguide was fabricated by K-ion exchange from a nitrate melt. Passively Q-switched pulses were achieved by placement of an
