Trichiasis, the misdirection of eyelashes arising from their normal sites of origin, may cause discomfort, corneal abrasions, ulceration and scarring. The therapies currently used for this condition have a variety of success rates and complications. In this report we describe epilation using a ruby laser to treat ten patients (11 lids). In six patients laser treatment was completely successful in achieving alopecia, in three patients the treatment was partly successful, and one patient was lost to follow up. In all cases ruby laser treatment was well tolerated, and there were no reported complications; thus, ruby laser treatment can be a viable and well-tolerated option for the relief of the symptoms of trichiasis.

To investigate the efficacy and safety of picosecond (PS) and nanosecond (NS) 1064-nm neodymium-doped yttrium aluminum garnet (Nd: YAG) laser in treating Café-au-lait macules (CALMs). We retrospectively analyzed the medical records of patients with CALMs, who were treated with PS or NS 1064-nm lasers from January 2020 to January 2022. The efficacy was determined based on the before and after pictures by two independent investigators.

Purpose: To compare the effect on sexual function of ejaculation-sparing enucleation of the prostate using Thulium: YAG laser (ES-ThuLEP) versus continuous-wave Thulium Fiber Laser (ES-ThuFLEP).
Methods: 112 patients with lower urinary tract symptoms secondary to benign prostatic hyperplasia who wished to preserve ejaculation were treated. 58 patients underwent ES-ThuLEP (Group A) using the Cyber TM generator.
A transversely isotropic diode-pumped solid-state laser is used to obtain an orthogonally dual-polarization nonplanar circular mode (NCM) under off-axis pumping in the strictly degenerate cavity. Each polarized component of the NCM outside the cavity is revealed to be individually localized on the ray orbits forming a nonplanar surface, in which the transverse patterns display multiple spots well positioned on a circular structure. An analytical representation is established to explore polarization-resolved components of the NCM by utilizing the Gaussian wave packet to directly correlate with geometrical rays.

With a compact Faraday rotation angle has been used in NPR mode-locked lasers, and we find that incomplete isolation of backward-propagating light does not hinder self-starting.

Background: We aimed to evaluate and compare the rise in the temperature for the safety of the kidney parenchyma on firing the Holmium: Yttrium Aluminium Garnet laser and the Thulium Fiber Laser during laser lithotripsy in humans.
Method: We included 30 pre-stented patients with renal calculi undergoing Retrograde intra-renal surgery. They were randomized into two groups - 15 patients underwent holmium laser lithotripsy and 15 patients underwent TFL laser lithotripsy.
