Diode-pumped microchip Er–Yb:glass laser

Optics Letters, 1993
A single-frequency, diode-pumped, Er-Yb:glass microchip laser at a 1530-nm wavelength has been designed and operated. An output power of greater than 25 mW, a linewidth narrower than 1 kHz, and a slope efficiency of 22% have been obtained.

Room-temperature diode-pumped Yb:YAG laser

Optics Letters, 1991
We have developed an efficient room-temperature ytterbium-doped YAG laser operating at 1.03 microm pumped by an InGaAs strained-layer diode laser operating at 968 nm. The threshold was 234 mW and 23 mW of output power was obtained for an absorbed pump power of 345 mW.

Diode-pumped Q-switched Yb:YAG laser

Optics Letters, 1993
A cw-pumped, repetitively Q-switched, InGaAs-diode-pumped Yb:YAG laser has been demonstrated at room temperature. An output energy of as much as 72 microJ/pulse at 1.03 microm with a pulse length as short as 11 ns (FWHM) was attained. No optical damage was observed despite the high saturation fluence (~10 J/cm(2)) of the Yb:YAG laser and the short ...

Diode-pumped cw bulk Er:Yb:glass laser

Optics Letters, 1991
ontinuous-wave laser operation of bulk Er:Yb:phosphate glass pumped at 980 nm by an InGaAs index-guided diode laser has been achieved for the first time to our knowledge, with 2 mW of output power obtained at 1.54 microm. To optimize pumping conditions and to investigate the effects of pump wavelength, the Er(3+):Yb(3+) glass disk has also been pumped ...

Diode-pumped Cr:LiSrAlF_6 laser

Optics Letters, 1991
A Cr:LiSrAlF(6) laser is diode pumped with both commercial 10-mW visible laser diodes and a higher-power 100-mW cw, 265-mW pulsed diode. Polarization combination of pump diodes to reach threshold is demonstrated with two low-power lasers. Pumping with the high-power diode produced powers of 19.9 mW cw and 78 mW pulsed.

Diode-pumped Nd:YLF regenerative amplifier

Optics Letters, 1992
A diode-pumped Nd:YLF regenerative amplifier operating at 1047 nm produces 88-microJ, 11-ps pulses at a 1-kHz repetition frequency. Switching of the 250-MHz seed pulses with a Pockels cell in the half-wave configuration is achieved with a contrast ratio of 20:1.
