“…Figure 4 illustrates the average output power and output pulse energy at 1176 nm with respect to the incident pump power for PRF of 20, 30, and 50 kHz. Reducing the PRF leads to a lower threshold for stimulated Raman output, but it leads to a smaller maximum output power due to the increasing thermal loading of the end-pumped Q-switched Nd-doped laser [22] . Moreover, the self-focusing-induced damage on YVO 4 crystal usually occurred especially at low PRF while the pump power is been over driving.…”

The efficient stimulated Raman scattering conversion in a diode-pumped actively Q-switched Nd:YAG laser was achieved with an undoped YVO 4 crystal as a Raman shifter. With an incident pump power of 16.2 W, 1176-nm first Stokes average output power of 2.97 W was generated at a pulse repetition rate of 50 kHz. The maximum pulse energy is higher than 83 µJ at both 20 kHz and 30 kHz. With mode-locked modulation, the effective pulse width far above threshold is usually below 5 ns. With an incident pump power of 7.62 W, the peak-power of 43.5 kW was demonstrated at 20 kHz.

Stimulated Raman scattering process in Nd:SrWO 4 crystal was employed to frequency down-shift the fundamental frequency of a Nd:YAG mode-locked laser system. A single-pass configuration of Raman crystal was investigated for this purpose. After that Nd:SrWO 4 laser was built and coherent pumping by alexandrite laser radiation was used. The simultaneous generation of stimulated Raman scattering was proofed for the case of Q-switching and mode-locking of Nd:SrWO 4 Raman cavity. For Nd:YAG 50 ps long (1064 nm) pulsed pumping a single-pass first Stokes maximum energy and conversion efficiency were 1.6 mJ and 25% , respectively. With the free-running Nd:SrWO 4 laser the maximum energy of 90 mJ at wavelength 1057 nm was obtained. Q-switching with the LiF:F − 2 saturable absorber gave up to 1.3 mJ energy at the first Stokes frequency (1170 nm) in the pulse length of 3 ns. In mode-locking regime (with saturable absorber ML51 in dichlorethan or 3955 in ethanol), the total generated energy was 1.8 mJ and 2.4 mJ for ML51 and 3955 dyes, respectively. The SRS output at 1170 nm was approximately 20% of those values.

“…), and broad band absorption and emision bandwidth, which enhances the flexibility on the diode pumping wavelength stability and therefore on the diode temperature control, as well as large emission bandwidth which is used to generate ultrashort pulses [8]. The Nd:KGW also has unique characteristics generating strong self Raman scattering [8,10] in various wavelengths including the eye-safe regime near 1540 nm. (8,11,12).…”

Diode pumping of a stress-free, Nd( 5 % at.):KGd(W04)2, grown by top nucleated floating crystal (TNFC) method, is presented. The diode-pumped laser was operated both in the free-running and passively Q-switched operating modes. Under optimized conditions ofresonator and optics, the disk (1.3 mm in thickness), produced at room temperature an efficient free-running, TEM00 output with maximum power of 0.4 W, with 75 % slope efficiency and 5 1 % total laser efficiency. The results presented here indicate the potential Nd: KGd(W04)2 crystals grown by TNFC growth method, as candidates for concentrated, stress free diode pumped microlasers in a large variety of wavelengths, including the eyesafe range.
