Abstract

método de calibração de energia de pulso de um dispositivo a laser, e, dispositivo a laser em um método de calibrar a energia de pulso de um dispositivo a laser (110) que provê radiação a laser de trabalho pulsada, a radiação a laser de trabalho é usada para realizar uma pluralidade de ablações de teste, em particular ablações de teste de múltiplos pulsos, em um ou uma pluralidade de objetos de teste (180) com uma energia de pulso diferente em cada caso. a profundidade de ablação de cada uma das ablações de teste é medida, e uma energia de pulso desejada associada é subsequentemente determinada com base nas profundidades de ablação medidas e uma profundidade de ablação desejada predefinida e é ajustada no dispositivo a laser. de acordo com a invenção, as profundidades de ablação são medidas por meio de um aparelho de medição interferométrica com óptica de coerência (130). a invenção ainda refere-se a um dispositivo a laser, em particular para executar o método anterior.
