摘要: Tunable lasers using color centers in alkali halide crystals are well established laser systems the near infrared spectral region (see e.g. [1] – [6]. The wavelength range from 0,8 µm up to almost 4 can, principle, be covered different types of various halides. This is shown Fig. 1 where emission bands displayed. Unfortunately, performance some (e.g. F2 +, (F2 +)*) not always ideal with respect generation desired centers, their stability during operation and shelf lifetime crystals. In particular, below 2.2 was difficult stable reliable center
