Diode pumped caesium laser

Multimode-diode-pumped gas (alkali-vapor) laser

“…[2] Subsequently, a diodepumped Cs laser was reported. [4] Since its pump source was a tunable master-oscillator / power-amplifier (MOPA) system, whose beam quality and brightness are also very high,…”

Theoretical analysis of the semi-ring and trapezoid LD side-pumped alkali vapor lasers

“…Pumped configurations have played an important role in enhancing the laser power of DPALs. Up to now, numerous experimental studies on DPALs with different pumped configurations were performed, including single-end pumped configuration [1,3,4,8], double-end pumped configuration [2,7], single-side pumped configuration with stable resonator [5] and unstable resonator [6]. Their corresponding models were set up by [9][10][11][12][13][14][15] and agreed well with the experimental results.…”

“…Diode-pumped alkali vapor lasers (DPALs), one of the lasers which are thought to have the potential to achieve high efficiency and high power in a high quality beam, have developed very fast during the past dozen years [1][2][3][4][5][6]. Especially since 2010, it has stepped into fluid age and reached $ kW level [7,8].…”

Alkali lasers for magnetic resonance imaging

“…That is why experiments with diode pumping of alkali lasers were always of great interest and importance. The first alkali (Cs) laser operating with a diode laser pump was demonstrated in 2005 [18]. We used a narrowband diode laser operating at 852 nm (SDL-8630, linewidth is less than 1 MHz) to longitudinally pump a 5 cm long Cs vapor cell.…”

“…They are either very complicated, expensive, low power and not efficient (Ti:Sa and Dye lasers) or too broadband with poor beam quality (diode lasers). The alternative light source is a new type of lasers, namely, diode pumped alkali vapor laser (DPAL) [4], which is under intensive development during the last several years [5][6][7][8][9][10].…”
