Demonstration of a 1-W injection-locked continuous-wave titanium:sapphire laser

Abstract

We report on a 1-W injection-locked cw titanium:sapphire ring laser at 846 nm. Single-frequency operation requires only a few milliwatts of injected power. This relatively simple and inexpensive system can be used for watt-level single-frequency lasers across most of the titanium:sapphire gain region. A brief review of injection-locking theory is given, and conclusions based on this theory indicate ways to improve the performance of the system.

Ultra Trace Determination Scheme for26Al by High-Resolution Resonance Ionization Mass Spectrometry using a Pulsed Ti:Sapphire Laser

“…19) Low repetition rate and cw injection seeded Ti:Sa lasers were reported previously. 20,21) In this work we present the development of an injection seeded Ti:Sa pulsed laser with repetition rate of up to 10 kHz. For characterization of its performance first RIMS investigations on stable 27 Al using the injection seeded Ti:Sa laser are discussed.…”

Stability Measurements of the Ca and Yb Optical Frequency Standards

“…To avoid broadening and shifts of the clock transition, it is necessary to tune the lattice wavelength close to its Stark shift-canceling value, which is near 759 nm for Yb. Light near this wavelength is generated with a Ti:Sapphire laser, which is injection-locked by a tunable diode laser [19]. The output of the Ti:Sapphire laser passes through an acousto-optic modulator for intensity control and an optical fiber for spatial filtering.…”

Development of a Continuous-wave 3-W 756-nm Injection-locked Ti:sapphire Laser

“…Injection locking is a useful technique that can achieve single-frequency operation of a high-power laser with good frequency stability comparable to that of a master oscillator [1][2][3]. Here, we demonstrate the injection locking of a 756 nm 3 W cw Ti:sapphire laser by use of a 50 mW injection laser.…”
