Preparation and Characterization of the Composite Nd:YAG/Nd:YAG Crystals
Crystal Research and Technology, 2023AbstractComposite crystals can not only improve the heat management of high‐average‐power laser considerably to obtain the high‐optical‐quality laser, but also be used to prepare larger size crystals. The composite Nd:YAG/Nd:YAG crystals with the size of 50 mm × 15 mm × 24 mm are prepared by thermal bonding technique using alumina balls as the pressure

The oscillation characteristics and dynamics of Nd:YAG long lasers are described. Nd:YAG laser cavities ranging in length from 1 m to over 6.3 km were constructed and operated. The development of laser oscillation, power output, active angular fields, and resonances of the circulating optical flux were monitored.

Frequency-modulated Nd:YAG laser
Optics Letters, 1991A frequency-modulated, single-mode Nd:YAG laser has been constructed that tunes up to 12 GHz. The laser incorporates a LiTaO(3) electro-optic phase modulator with acoustic damping to provide a tuning sensitivity of 12 MHz/V and linear voltage-to-frequency conversion. A frequency excursion of 1.2 GHz has been generated with a rise time of 0.6 ns.

Laparoscopic Myolysis with the Nd:YAG Laser
Journal of Gynecologic Surgery, 1993Laparoscopic myomectomy can be carried out in cases of subserosal and intramural fibroids. Laparoscopic myolysis can be proposed as an alternative to laparoscopic myomectomy in cases of large or multiple intramural fibroids in women aged over 40 or not desiring to bear more children but wishing to avoid a future hysterectomy.

We report on a monolithic resonator single-crystal Nd:YAG fiber laser. The laser resonator structure is simply formed by the fiber waveguide and the polished and coated fiber endfaces. The fiber oscillator is 6.5 mm long with a mean diameter of 47 μm. The lowest-order spatial mode for such a fiber has a beam waist of 15 μm, implying a Rayleigh length ...

The Nd:YAG laser in caries removal
British Dental Journal, 1994This paper shows how a laser can be used in the various stages of caries removal prior to the placement of a glass-ionomer restoration. In the future the laser may prove to be a valuable tool in enabling the dentist to perform surgical procedures with maximum comfort to the patient.

The Nd:YAG Laser Treatment of Hemangioma
Journal of Clinical Laser Medicine & Surgery, 1994An Nd:YAG laser was used in the treatment of 160 patients with hemangioma from January 1989 to January 1993. Irradiance was between 800 and 1600 W/cm 2 with energy between 400 and 1600 J/cm 2. The best results with almost total restoration were obtained in 21 of the 160 patients (13%).

Monolithic integrated Nd:YAG laser
Optics Letters, 1990By application of the technique of optical contact, a novel type of frequency-stable solid-state laser resonator has been developed. A diode-laser-pumped, monolithic integrated twisted-mode-cavity Nd:YAG laser with 80 mW of single-frequency output power at lambda = 1.06 microm has been fabricated. A linewidth below 10 kHz has been measured for the free-

Clinical experience with the Nd:YAG laser
American Intra-Ocular Implant Society Journal, 1984This study presents the results and complications of 389 patients who were treated with the Nd:YAG laser between September 1982 and November 1983 with at least a six-month follow-up. The majority of patients had a secondary discission of the posterior capsule.
