摘要： A solid state gain medium (32) is disposed between two mirrors (34, 36) to form a resonant cavity, the cavity length selected so that the gain bandwidth (12, 14) of the gain medium is less than the frequency separation of the cavity modes (16-24). By selecting this cavity length, only a single longitudinal mode will oscillate when the laser operates in a single transverse mode. The microlaser is optically pumped by any appropriate source such as a semiconductor injection laser or laser array. Suitable gain media are Nd:YAG and Nd pentaphosphate.

摘要： An optical parametric oscillator/laser system includes an optical pump source for generating pump radiation and an embedded dual optical resonator containing an optical parametric oscillator/laser crystal. The embedded dual optical resonator includes a laser resonator and an optical parametric oscillator resonator. The OPOL crystal is an optical parametric oscillator material doped with ions that exhibit lasing transitions. The pump radiation stimulates generation of laser radiation. When the laser radiation reaches the parametric threshold, optical parametric radiation is generated. In one embodiment, the laser resonator and the OPOL resonator are each defined by spaced-apart mirrors. In another embodiment, the OPOL system includes an OPOL rod having end caps at each end. Each end cap includes surfaces for internally reflecting the laser radiation and the parametric optical radiation in a closed loop path so that the OPOL rod and the end caps define an optical resonator. The parametric radiation of the OPOL system is tunable over a broad wavelength range.

C. and at about 370.degree. C. After the solution has been held at 500.degree. C. for about 12 through 15 hours, a preformed substrate monocrystal of gadolinium yttrium penta-ultraphosphate is introduced thereinto and a layer of monocrystalline neodymium yttrium penta-ultraphosphate is grown thereon.
