Tunable perovskite microdisk lasers
Nanoscale, 2016Perovskite microdisk lasers have been intensively studied recently. But their lasing properties are usually fixed once the devices are synthesized. Here, for the first time, we demonstrated the switchable and tunable perovskite microdisk lasers by surrounding them with 5CB liquid crystals.

Optics Letters, 2018
In this Letter, for the first time, to the best of our knowledge, a pulse and CW laser based on an Er-doped Gd3Ga2.7Al2.3O12 (Er:GGAG) active medium emitting laser radiation at 2.8 μm are presented. With the longitudinal diode pumping, the maximal output energy of 4.9 mJ and slope efficiency of 13.5% in the pulse regime were reached.

Pulsed tunable lasers in cytofluorometry
The Histochemical Journal, 1974A tunable dye laser which generates pulses of high intensity (107 W cm−2) and short duration (2 nsec) was used in an experimental set-up for cytofluorometry. The fluorescence signal given by a single cell (frog erythrocytes stained by a conventional Feulgen reaction for the demonstration of DNA) has been studied. This system allows, for the first time,

Optical Society of America Annual Meeting, 1990
The tutorial will begin with a discussion of the underlying physics of tunable solid-state laser media. A review of specific systems, including alexandrite, Ti:sapphire, and Co:MgF2, will follow and will include information on modes of operation and operating characteristics of each mode.

Widely Tunable Semiconductor Lasers
Optical Fiber Communication Conference, 2014Widely tunable semiconductor lasers have become a mainstay for metro and long-haul transmission. This tutorial addresses the unifying principles underlying the plethora of device architectures in use today, with focus on monolithic integration to meet demanding application requirements.

Physical Review A, 1994
The possibility of constructing tunable x-ray lasers of photon energy in the kilo-electron-volt range is discussed. It is shown on the basis of channeling observations that an \ensuremath{\sim}3.3% change of the photon energy of an x-ray-laser scheme proposed recently can be obtained with a 100-K change of the temperature.
