Shardlow PC, Minassian A, Damzen MJ, 2011, Coherent beam combining of self-adaptive lasers, Pages: 1106-1107

The novel technique of phase conjugate self-organised coherent beam combination is reported. It is demonstrated that due to the spectral mode freedom of a phase conjugate self-adaptive laser that efficient "all-passive" combination of many high quality lasers can be achieved. Efficient combination (>92%) of two modules has been experimentally demonstrated to >30W in continuous wave operation. Recent results demonstrating pulsed operation are also reported. © 2011 IEEE.

Frequency doubled vortex laser based on the side-pumped Nd;YVO 4 bounce laser was demonstrated, for the first time. Maximum powers of frequency-doubled vortex output in CW and Q-switched regimes reached 105 mW and 3.8 W, respectively. © 2011 IEEE.

Arbabzadah EA, Chard SP, Amrania H, Phillips CC, Damzen MJet al., 2011, High energy diode pumped Er:YSGG laser at 3m transition

Lasing of the trivalent erbium ion in garnet hosts at wavelengths close to 3m has attracted considerable interest. This is primarily due to the strong absorption by water around this wavelength, making erbium doped lasers suitable for use in a range of medical and biological applications [1-3]. A variety of erbium doped hosts have been investigated to date, of which Er:YAG has been the most intensively researched. However, Er:YSGG shows promise for the construction of a more efficient laser system owing to its longer upper laser level lifetime of 1.3ms compared with 0.12ms in Er:YAG [1]. In this work we report operation of a quasi continuous wave (QCW) diode pumped 30 at. % Er:YSGG laser in the bounce geometry, yielding pulse energies of up to 41mJ and a slope efficiency of 12.6%. © 2011 IEEE.
