✦ Synopsis

We report a diode-pumped Nd:YAG laser emitting at 899 nm based on the 4 F 3/2 -4 I 9/2 transition. A power of 1.04 W at 899 nm has been achieved in continuous-wave operation with a fiber-coupled laser diode emitting 19.2 W at 809 nm. Furthermore, intracavity second-harmonic generation in continuouswave mode has also been demonstrated with a power of 284 mW at 449.5 nm by using a BiB 3 O 6 (BiBO) nonlinear crystal. The fluctuation of the blue output power was better than 2.8%. The beam quality M 2 value is 1.3.

Efficient and compact blue laser output at 468 nm is generated by intracavity frequency doubling of a continuouswave (CW) diode-pumped Nd:CNGG laser at 935 nm. With 17.8 W of diode pump power and the frequency-doubling crystal BiB3O6 (BiBO), a maximum output power of 490 mW in the blue spectral rang

We describe the output performances of the 942 nm 4 F 3/2 → 4 I 9/2 transition in Nd:GSAG under diode-laser pumping. An end-pumped Nd:GSAG crystal yielded 3.7 W of continuous-wave output power for 17.8 W of absorbed pump power. The slope efficiency with respect to the absorbed pump power was 23.4%.

We present for the first time laser architecture to obtain continuous-wave yellow radiation at 594 nm. The choice of crystals (Nd:LuVO 4 for emission at 1343 nm and Nd:YAG for emission at 1064 nm) was guided by laser performance. A part of the pump power was then absorbed by the Nd:LuVO4 crystal, th

We report an electro-optical Q-switch ultraviolet laser at 355 nm with narrow width and low repetition rate generated by pulsed-diode side-pumped Nd:YAG/KTP/LBO. The single-pulse energy is measured to be 18.7 mJ with a pulse-width of 7.32 ns at a repetition rate of 1 Hz and a pump current of 120 A.
