A single-frequency crystalline Raman master oscillator power amplifier (MOPA) at 1178 nm was demonstrated. The pump source was a homemade single-frequency 1062 nm Nd:GGG MOPA system with a pulse width of 104 ns. The BaWO4 Raman oscillator generated seed radiation at 1178 nm with a pulse energy of 7.7 mJ. The highest amplified Raman pulse energy of 41.0 mJ was obtained with a pulse width of 44.1 ns. The linewidth was less than 500 MHz.

“…It has a high optical damage threshold (> 1.2 GW/cm 2 for 8 ns at 1064 nm) [1] and a high second-order nonlinear coefficient (d 33 = 16.2 ± 1 pm/V measured with second harmonic generation of 1064 nm) [2]. It has been widely used in expanding the frequency range of lasers through nonlinear conversion processes, including second harmonic generation [3,4], sum frequency generation [5], difference frequency generation [6], and optical parametric oscillator [7][8][9]. By using its third-order nonlinear effect, Raman lasers have been obtained [3,[9][10][11].…”

A terahertz parametric oscillator based on KTiOAsO(4) crystal is demonstrated for the first time. With the near-forward scattering configuration X(ZZ)X + Δφ, the polarizations of the pump, the Stokes and the generated THz waves are parallel to the z-axis of the crystal KTA. When the incident angle θext of the pump wave is changed from 1.875° to 6.500°, the THz wave is intermittently tuned from 3.59 to 3.96 THz, from 4.21 to 4.50 THz, from 4.90 to 5.16 THz, from 5.62 to 5.66 THz and from 5.92 to 6.43 THz. The obtained maximum THz wave energy is 627 nJ at 4.30 THz with a pump energy of 100 mJ. It is believed that the terahertz wave generation is caused by the stimulated scattering of the polaritons associated with the most intensive transverse A(1) mode of 233.8 cm(-1). Four much weaker transverse A(1) modes of 132.9 cm(-1), 156.3 cm(-1),175.1 cm(-1), and 188.4 cm(-1) cause four frequency gaps, from 3.97 THz to 4.20 THz, from 4.51 to 4.89 THz, from 5.17 to 5.61 THz and from 5.67 to 5.91 THz, respectively.

“…By using the second-order nonlinearity v (2) [1] and the third-order nonlinearity v (3) [2], multi-wavelength radiations have been realized. Especially, the combination of using v (2) and v (3) in a single nonlinear crystal has received much attention recently [3][4][5][6][7].…”

By using a doubly passively Q-switched Nd:Gd 3 Ga 5 O 12 (Nd:GGG) laser with Cr 4? :YAG and GaAs as saturable absorbers as pump laser, simultaneous intracavity optical parametric oscillation and stimulated Raman scattering based on a single X-cut KTiOPO 4 (KTP) crystal have been realized. Under an incident diode pump power of 10.5 W, the output powers at the signal wave near 1,569 nm and the first Stokes emission near 1,094 nm were 218 and 72 mW, corresponding to the optical-to-optical conversion efficiencies of 2.08 and 0.69 %, respectively. The measured shortest pulse duration at the signal wave near 1,569 nm was 580 ps, generating a pulse peak power of 43.7 kW, while the minimum pulse duration at the first Stokes emission near 1,094 nm was 1.61 ns. By adjusting the tilt angle of the KTP crystal, up to the third Stokes scattering was also obtained.
