A Hybrid Self-Seeded Ti:sapphire Laser with a Pumping Scheme Based on Spectral Beam Combination of Continuous Wave Diode and Pulsed DPSS Lasers

Continuous wave, 30 W laser-diode bar with 10 GHz linewidth for Rb laser pumping.

A laser-diode bar incorporated into an external cavity with a volume Bragg mirror produced 30 W of cw output power within a 20 pm (10 GHz) spectral linewidth (FWHM) centered at 780 nm. The device output power exceeded 90% of that for the free-running laser-diode bar. The emission wavelength was tuned over a 400 pm range without broadening laser spectrum width. Absorption of 90% of the laser rad...

Laser-assisted hair removal: comparison of long-pulsed alexandrite and long-pulsed Nd:YAG lasers, individually and in combination

Background and aim: Laser is one of the most recent techniques which has widespread use in the treatment of many skin diseases. This technique has been successfully used to remove unwanted hairs in hirsutism. The aim of this study was to evaluate and compare the efficacy and safety of long-pulsed 755 nm alexandrite and long-pulsed 1064 nm Nd: YAG lasers individually and in combination for perma...

Spectral beam combining of diode lasers with high efficiency

Based on spectral beam combining we obtain 16 W of output power, combining two 1063 nm DBR-tapered diode lasers. The spectral separation within the combined beam can be used for subsequent sum-frequency generation. OCIS codes: (140.2020) Diode lasers; (140.3298) Laser beam combining; (190.2620) Harmonic generation and mixing

CW THz Wave Generation System with Diode Laser Pumping

Analysis of thermal therapy using infrared diode lasers operated in continuous wave and pulsed mode

The design (software control) guidelines are presented for medical laser systems based on the analysis of the tissue temperature response to various lasers at both cw and pulsed modes. By solving the laser volume-heating diffusion equation, we analyze the roles of various laser and tissue (or water) parameters on the laser-heated solution temperature profiles, including laser intensity, pulse-w...
