Spectroscopy and stimulated emission of Nd3+ in an acentric CsY2F7 host

The results of preliminary spectroscopic studies of new fluoride single-crystal CsY2F7 that is activated by Nd3+ ions are given. Direct evidence for the possibility of application of this ordered material as a laser host is given for the first time to our knowledge. Stimulated emission of Nd3+ ions on the main intermultiplet transition is obtained under both nonselective flash-lamp pumping conditions and continuous Ar ion laser pumping conditions. © 1992 Optical Society of America

Spectral-kinetic and lasing characteristics of new Nd3+-activated laser hosts of the KF–YF3 system

The results of the investigation of two new laser hosts are reported. Stimulated emission from Nd3+ ions has been observed for the first time in the two ordered fluoride crystals of the KF–YF3 system: KYF4 (FYK) and K2YF5 (PYFK). The major luminescent and lasing characteristics of the crystals are presented. The stimulated emission spectrum features and application prospects of the new laser hosts are discussed. © 1990 Taylor & Francis Ltd

Direct and passive subnanosecond pulse-train generation from a self-injection-seeded ultraviolet solid-state laser

We propose a passive self-injection-seeding scheme for the generation of short-pulse trains from various pulsed lasers. In this scheme a single subnanosecond pulse is generated from a short-cavity seeding laser. The pulse is then returned to the same gain medium and amplified regeneratively until the gain is quenched completely. Cw operation capability or an external short-pulse seeding laser is not required for generation of short-pulse trains. Based on this simple scheme an ultraviolet subnanosecond pulse train is directly and passively generated from a solid-state laser medium (Ce3+:LuLiF 4) pumped by a standard 10-ns laser. © 1995 Optical Society of America

Subnanosecond tunable ultraviolet pulse generation from a low-Q, short-cavity Ce:LiCAF laser

We have developed an all-solid-state tunable ultraviolet laser system employing recently developed Ce:LiCAF, a new degradation-free tunable ultraviolet laser medium pumped by the fourth harmonic of a conventional Q-switched Nd:YAG laser. The low-Q, short-cavity Ce:LiCAF laser produced satellite-free subnanosecond pulses in a tuning range of 281 nm to 297 nm under appropriate pumping-fluence control

Ultraviolet short pulses from an all-solid-state Ce:LiCAF master-oscillator-power-amplifier system

We have developed an all-solid-state master-oscillator-power-amplifier system employing Ce:LiCAF, a new degradation-free tunable ultraviolet laser medium pumped by the fourth harmonic of conventional 10-ns Q-switched Nd:YAG lasers. The low-Q, short-cavity Ce:LiCAF master oscillator produced a satellite-free 1-ns pulse under appropriate pumping-fluence control. 18% energy extraction with sufficient gain was achieved in a single-stage, confocal, double-pass amplifier. As a result, 289-nm, 1-ns, 14-mJ pulses were efficiently obtained from this simple laser system. © 1997 Optical Society of America

Ultraviolet picosecond pulses from an all-solid-state Ce:Flouride master oscillator and power amplifier system

290-nm, 590-psec, 300-μJ pulses are obtained from a Ce:LiSAF/Ce:LiCAF MOPA system pumped by the fourth harmonic of a Nd:YAG laser

Ce3+-Activated Fluoride Crystals as Prospective Active Media for Widely Tunable Ultraviolet Ultrafast Lasers with Direct 10-ns Pumping

New possibilities have been investigated for recently developed solid-state tunable ultraviolet (UV) laser materials such as Ce+ ion-activated LuLiF4 (LLF) and LiCaAlF6 (LiCAF). With their broad-gain width, demonstrated reliability, and high efficiency, they are attractive for ultrashort pulse generation and amplification. To prove that, we have demonstrated UV picosecond-pulse amplification using Ce : LLF. For such new laser materials, we proposed a passive self-injection seeding scheme for the direct generation of short-pulse trains, which does not require CW-operation capability or an external short-pulse seeding laser. Using this simple scheme, a UV sub-nanosecond pulse train is directly and passively generated from Ce:LLF pumped by a standard 10-ns KrF excimer laser, and Ce : LiCAF pumped by the fourth harmonic of a conventional 10-ns Q -switched Nd : YAG laser. © 1995 IEE
