A method and apparatus is provided for producing near-diffraction-limited laser light, or amplifying near-diffraction-limited light, in diode pumped alkali vapor photonic-band-gap fiber lasers or amplifiers. Laser light is both substantially generated and propagated in an alkali gas instead of a solid, allowing the nonlinear and damage limitations of conventional solid core fibers to be circumvented. Alkali vapor is introduced into the center hole of a photonic-band-gap fiber, which can then be pumped with light from a pump laser and operated as an oscillator with a seed beam, or can be configured as an amplifier.

The recent work at LLNL on alkali-atom lasers has been remarkably successful and productive. Three main phases (so far) can be identified. First, the concept and demonstration of red lasers using (Ti:sapphire pumping) took place; during this time, Rubidium and Cesium resonance-line lasers were tested, and theoretical models were developed and shown to describe experimental results very reliably. Work done during this first phase has been well documented, and the models from that period are still in use for their predictions and for designing power-scaled lasers. [1 - 3] Second, attempts were made to produce a blue alkali-vapor laser using sequentially-resonant two-step pumping (again, using Ti:sapphire lasers.) Although a blue laser did not result, the physical limitations of our approach are now better-defined. Third, diode-pumped operation of a red laser (Rubidium) was attempted, and we eventually succeeded in demonstrating the world's first diode-pumped gas laser. [4] Because we have a defensible concept for producing an efficient, compact, lightweight, power-scaled laser (tens of kW,) we are in a position to secure outside funding, and would like to find a sponsor. For descriptions of work done during the ''first phase, '' see References [1 - 3] ''Phase two'' work is briefly described in the section ''Blue laser, '' and ''phase three'' work is presented in the section entitled ''Diode-pumped red laser.''

We report the first demonstration of a multimode-diode-pumped gas laser--Rb vapor operating on the 795 nm resonance transition. Peak output of (almost equal to)1 Watt was obtained using a volume-Bragg-grating stabilized pump diode array. The laser's output radiance exceeded the pump radiance by a factor greater than 2000. Power scaling (by pumping with larger diode arrays) is therefore possible.

The objective of this program was the study and exploratory development of a miniature solid state laser source as a potential signal source in a variety of fiber optic sensors and systems. The specific source to be studied was composed of a single-crystal Neodymium-YAG optical fiber end-pumped with a single semiconductor laser diode.

The UNM portion of this program focused on two areas, namely: (1) Efficient, wavelength-switchable fiber lasers for Air Force applications; (2) The development of mid-IR sources, namely 3 micrometers fiber lasers for pumping longer wavelength sources for IRCM applications. More specifically, we developed and/or demonstrated: (1) A precisely and rapidly wavelength-switchable 1.5 micrometers fiber laser source with switching times of ^18 microseconds; (2) A widely tunable wavelength-selectable fiber laser for 8 channels using an FBG string for channel pinning with output powers of each channel of ^l2 dBm(16 mW); (3) A broadly tunable wavelength-selectable source using a fiber Sagnac loop filter, with over 25 wavelength-switchable channel outputs with precise 50 GHz channel spacing, excellent output power uniformities of +/- 0.8 dB over the whole tuning range, and very large (65 dB)side mode suppression ratios; (4) A single-mode tunable wavelength selectable fiber laser operating at 8 uniquely selectable wavelength-channels with individual linewidths of 300 kHz in each channel 5. That the optimal pump wavelength for 'the 800 nm pump band' pumping of high-power 3 micrometers mid-IR fiber laser is 799 +/- 1 nm (as opposed to earlier reports implying an optimal pump wavelength of 791 nm); (6) Optimal designs for custom double-clad Er:ZBLAN fibers for power scaling of such mid-IR lasers to average powers of 10 Watts 7. Compact diode-pumped Q-switched (both actively and passively) mid-IR fiber lasers.
